A new version of GeeXLab is available for all platforms: Windows (32-bit, 64-bit), Linux (64-bit), Mac OS X and Raspberry Pi (Raspbian).
Don’t know what to do with the 7-inch touchscreen display you bought for your Raspberry Pi? Transform it in a clock.
Here is a ready-to-use GeeXLab demo (OpenGL ES 2.0), that displays a clock.
The wizard behind Shadertoy has struk once again with this beautiful demo showing an animated snail.
