Welcome and a most jolly July to all! It's Friday once more and the topic is text as a visual art. A very early example of combining text and graphics into a single artistic statement is the art of illuminated manuscripts. The handwritten letters were embellished with beautiful patterns and decorations that blended illustration with calligraphy. Concrete Poetry is a form in which the placement of the words on the printed page is used to convey and accentuate the poetic content. Concrete poetry evolved into (and overlaps) a form known as Visual Poetry in which the text may form an image, further reinforcing the intent. A modern web-page is an example of how content and style interact and combine. The idea is to emphasize the words by selecting their placement, font, size/weight, color and other attributes. The good news for those wanting to create their own visual/concrete poetic masterpiece is that it takes little more than a PC and a decent word processing or publishing program. Try composing an ode to nature in the shape of a tree or a minimalist sonnet that forms a neat triangle or square of text.

Greeting and Happy Independence Day! It's a hot summer evening and I'm back with more stuff of interest to computer geeks and artists of all types. The topic for tonight is music and I'm going to discuss recording and using your own simple samples. For this exercise I used a cheap headset microphone, a small plastic soda bottle and the excellent Audacity open-source sound editing program. If you're trying this on your own PC make sure the mic is plugged into your PCs sound card before you begin. I started up Audacity, got the mic positioned and pressed the “record” button from the row of icons near the top. To make the a sound to record I simply blew over the mouth of the bottle to make a nice hollow note. Press the stop button to end the recording and you've got a raw sound file. I was able to trim the sample, tune and adjust the pitch and save it as a WAV file within Audacity. I repeated the process a couple more time with varying amounts of water added to the bottle to produce a higher pitched note. Once I had 3 samples, I was able to import the WAV files into the Orion sampler. The sampler will automatically detect and map your samples to a range of notes. Finally, we're ready to play the samples as an instrument either with a MIDI controller or through step-editing. It's fairly easy, and very fun and you can get some unique and highly usable sounds from this technique. If you haven't done it yet, give it a try.

The loops of the week were created from the previously mentioned bottle samples.
The book of the week was “3D Toons” by Steve and Raf Anzovin. It isn't a detailed guide to creating toons but it has some excellent and varied examples from different artists. This book was also my bargain of the week, cause I got it at the local 99 Cents Only Store for the princely sum of $0.99!

Hello Again! It's another lovely warm summer night here in the old gray cat's loft, and I'm here with more stuff to share. The topic for this session is Graphics and the focus will be on a very useful 3D technique. I've been working on a project in Anim8or that required some facial animation. I decided to make use of morph targets to move the characters mouth, eyelids and eyebrows in a convincing manner. To use morph targets you define the start and ending positions for the points (vertexes) of a 3D object. The rendering software can then fill in the intermediate in-between positions, creating a smooth animated sequence. It's just the thing for lip-syncing recorded speech to an animated mouth. One of the drawbacks to this technique is that it becomes unwieldy when dealing with more than a few points. A partial solution is to define your object as a subdivision or spline surface, reducing the number of points to translate. Try it for yourself the next time you need add a bit of expression to your animation.

The loops of the week are a set of synthesized samples.
The PC game of the week was Travian once more. I've been recruited into an alliance and now stand a significantly better chance of survival.
The Movie/DVD of the week was “Hellboy”
The diversion of the week was Sudoku.

Greetings! We're on the verge of summer and the topic for this hot evening is games. I'm going to focus on a couple of free/open source clones of classic turn-based strategy games. I'll start the session with FreeCiv, a very faithful reproduction of Sid Meier's classic Civilization II. I like the tough AI, wide range of options and depth in FreeCiv. I don't like the long time it takes to play but that's common of most good 4X strategy games. The graphics are clear, but 2D and a bit understated. You really don't need 3D gob-smacking graphics to enjoy Freeciv, just a good brain and lots of time and patience. The other freebie find of the week is Empire Allegro Advance; A Windows clone of the popular Game Boy Advance title Advance Wars. I like the cartoony graphics, the low system requirements, and the fact that it comes with a map editor and source code. I don't like the slightly cheesy vibe of the project and the fact that it is too easy to beat the computer opponents. I'll have more of my favorites on display here in later posts. In the meantime, give them a try and have some fun!

The loops of the week are some more beat-sliced drum loops.
The PC game of the week is still Future Pinball. My favorite table is the recreation of Bally's Wizard from 1975. The last electro-mechanical tables from the mid 70s were the best IMHO.
The movie/DVD of the moment is “Juno”.

Hello and Happy Friday the 13th! Tonight's timely topic is music and I've an interesting technique to share. In past blog entries I've described the use of looping in music to create pieces from short instrument or synthesized samples. Beat slicing is a related electronic music technique, in which a loop or sample is divided into separate beats, usually some even increment such as 1/16. Each subdivision can now be played independently of the other so that you can now play the entire phrase at a different tempo with little of the distortion associated with time stretching. You can also reorder the segments (slices) to get a completely different musical loop. Beat slicing is most often used on drum patterns, but you can also use other instruments or vocal loops for different effects. The first and most famous beat slicing tool is ReCycle, but you can use a number of different music applications and plug-ins to get the job done. My advice to the uninitiated is, as always, to try it and see if you like it.

The PC game of the week is Future Pinball. Future Pinball is a both a detailed emulation of a real pinball table and a flexible construction set. The coolest thing is that it's a free program. The 2nd coolest thing is that there are a lot of user-designed recreations of classic tables available for download.
The book of the moment is The Art of Computer Programming volume 1 by Donald Knuth.

Greetings again! The topic for tonight is graphics and the focus is on creating your own extensions for Project Dogwaffle. I recently acquired and started using the tBDW thinBasic Dogwaflle scriptable interface. This package allows you to create your own plug-ins for Project Dogwaffle using the ThinBasic scripting language. There are only about a half dozen statements and a like number of equates to get your head around, so getting started is relatively easy. Your thinBasic script can either render a completely new picture or modify an existing one. I've written some simple scripts to convert color pictures to b&w and to generate mathematical patterns. It's fast, fun, and easy so I'll recommend it to anyone looking to expand the basic functionality of PD.

Friday Greetings! It's another nice late spring evening and I'm back with more of the good stuff. Tonight's topic is computing and I'll focus on portable applications. A portable application is a program that can be that can be installed and carried around on a portable storage device and used on any Windows computer. What this means is that you can take a small suite of your most used programs on a handy USB flash drive or portable hard drive and have them ready to work wherever you go. PortableApps.com has collected a number of free/open-source programs with a handy launcher application. The set includes portable versions of Mozilla Firefox, the OpenOffice.org productivity package, and ClamWin anti-virus. Being the artist/musician/geek that I am, I was also interested in graphics, games, programming and music applications. For 2D drawing you can use GIMP, or Project Dogwaffle. For 3D graphics, Anim8or and a few different portable versions of Blender are available. For music you can use the brilliant and free Audacity sound editing application. For games you have a fair selection of low calorie, limited resource options to choose from. Programmers can use the Decimal Basic programming language to create small applications. As an exercise I put together a bunch of portable stuff that took up only about ½ of a 2gb flash drive. It's perfect for computing and creating away from home. Give it a try!
