I'm a big fan of making the hardware do as much as possible, so when I needed to do a layered animation I decided to to it all in the shaders. So this 'Cylon' effect you see is a single texture animated in a shader. The cpu is not used at all other than to setup the effect.
This effect is being shown in Cyberstream Fugitive which is currently going through Kickstarter and can be found here: http://www.kickstarter.com/projects/7...
