- MilkDrop 2 is here! Now shipping with Winamp 5.5.
GEISS homepage
Watch the sound waves ebb, flow, and bend as you fly through a dreamlike realm of sight and sound. Download the Winamp plug-in version to run it using Winamp and mp3's, or get the stand-alone screensaver, which can react to the microphone, a CD, or your computer's stereo mix.
This was my first Winamp music visualization plug-in, released in 1998, and quickly became a popular favorite; to date, it's been downloaded over 3.5 million times, just from winamp.com.
MILKDROP homepage
Similar to Geiss, MilkDrop takes the viewer on a surreal journey through sound waves. However, because it utilizes the graphics processing unit (GPU), MilkDrop is much faster. It is also far more flexible, allowing non-programmers to tune it and tweak it and generate new effects. This has spawned a huge community of people authoring many thousands of presets for it, each giving it a different look, and reacting to the music in ways I never dreamed of. Thanks to this preset authoring community, MilkDrop continues to evolve to this day.
MilkDrop was first written in 2001. Before MilkDrop 2 replaced it, the original MilkDrop shipped with Winamp by default for several years. The original MilkDrop is open-sourced over at SourceForge.
SMOKE homepage screenshots
Watch the swirling smoke as it moves to the music, with beat-driven jets of smoke colliding and eddying in realtime. For Winamp. Also runs as wallpaper (Desktop Mode).
MONKEY homepage screenshots
A journey through a never-ending network of randomly-generated caves, with various shading and texturing options, and a great 3D mode (for use with colored glasses).
GEISS 2 homepage screenshots
A remake of the original Geiss visualizer, with new features, including the ability to run as wallpaper ('Desktop Mode') and at higher resolutions than the original. However, I didn't spend as much time tweaking the colors and motions in this one, so I (and many others) still prefer the original.
GEOFORMS homepage screenshots
A screensaver I wrote at Nvidia, featuring richly-shaded, music-driven metaballs (or blobs) with a psychedelic, procedural background (kind of like Geiss running on a cubemap). Lots of hi-tech graphics features such as HDR motion blur, depth peeling, refraction, procedural noise and marble, and more. GeForce 7800 recommended; GeForce 6000 or later required.
Here's a cool Youtube video somebody shot of the demo.
MILKDROP 2 homepage screenshots
A major upgrade to the original MilkDrop visualizer, this beastly little program opens up the power of modern graphics chips and programmable pixel shaders to the realm of music visualization. Pixel shaders allow dozens, even hundreds of complex instructions to be executed for every pixel on the screen, every frame. Other new features include jpg textures, gaussian blurring, a preset "mash-up" feature, and a prest "back" button. MilkDrop 2 is backwards-compatible with presets from MilkDrop 1.
Now shipping with Winamp 5.5.
Works with any graphics processor, but to see the newest effects, you need a GeForce 5700 or Radeon 9600 (or better).
DREMPELS homepage
A hallucinatory desktop enhancer - bring your wallpaper to life with graceful, swirling imagery. Runs beautifully as animated wallpaper, or as a screensaver. Insanely low CPU utilization.
CASCADES homepage screenshots video
This is an advanced graphics demo I wrote at Nvidia for the GeForce 8800, where you can build your own waterfalls (CTRL+click) and watch them cascade down an endless, procedurally-generated, richly-shaded rock structure. Requires Windows Vista and a GeForce 8-series or later.
If you want to know how the special effects were done, check out the powerpoint slides from our talk at GDC ('NVIDIA Demo Team Secrets - Cascades'). Or for a quick overview, check out a brief blog entry I made about the demo.
How Many Animals Do We Eat?In the U.S., 31 animals per person, each year, or 2,400 animals during an average individual's lifetime. This does not include seafood, but does count poultry, which make up over 95% of the numbers. Unfortunately, food animals have almost no protection in the U.S., and most spend their entire lives on factory farms, in conditions just sufficient to keep them alive. However, free range meat is slowly but surely growing in demand, as individuals learn more and decide the few extra bucks is worth it.
Click here for a breakdown by type of animal.

The Veggie GuideMy 19-page primer on a holistic and humane diet. Ever wondered, if you don't eat meat, what do you eat? This guide addresses that (thoroughly), and gives you everything else you need to know about eating well without killing anything that sleeps, dreams, feels pain, has a mother, loves its young, or had a face.

My suggestions on how to reduce your material and energy consumption, as well as material waste, to leave a better world for future generations. I consume about 1/4 the electricity, and produce 1/10th the garbage, that I did just five ago! Here's how...
CarbonFundMost of us drive a car, burning an average of 10,000 pounds of CO2 each year, which contributes to global warming. But for about $50 (tax-deductible), you can make your car CO2-neutral for the year by financing projects to sequester 10,000 pounds of CO2 during the year. Very clever, and very cheap! (...twice as effective as buying a hybrid, and FAR less expensive!)
I used to recommend Terrapass, but now recommend Carbonfund for several reasons. First, they have better prices (per ton CO2). Second, they're a nonprofit (which also means you can deduct your donation).

Green TagsGreen Tags (also known as Renewable Energy Credits) are a way to directly subsidize clean, renewable electricity. You can even buy them online. $20 funds the production one Megawatt-hour (the average household consumes 10 a year), which prevents 1,400 pounds of carbon dioxide (a greenhouse gas) from entering the atmosphere.
You can visit the Bonneville Environmental Foundation to buy green tags.
An article I wrote on renewable energy; a little bit outdated at this point.
ANAK A program I wrote to help people learn to play (or compose!) Gamelan music. It actually plays songs from notation, and highlights the currently playing notes. You can also adjust the volume of all the instruments in the orchestra - even the sangsi vs. poulos parts - so you can isolate parts and hear (learn) them better. Comes with six songs that are part of Gamelan Anak Swarasanti's set list.
