Shown off this weekend at Revision 2014 in Saarbrücken was "The Timeless", an interesting OpenGL tech demo with the compiled binary coming out to just 64kb in size -- including all assets. This demo is visually amazing, regardless of file size. Unfortunately, there's only a Windows binary available at this time, but given that it's written against OpenGL, hopefully a Linux port will be released soon (I'm trying to get in contact with the demo's author) -- but regardless, the demo is worth checking out with a video being available embedded below.
This 64kb OpenGL tech demo is written against the OpenGL 4.3 specification. Under Windows it seems to only work with NVIDIA hardware at the moment due to the Catalyst binary driver not supporting GLSL uniform default values. Those wishing to run this demo in real-time are recommended to use a NVIDIA GeForce GTX 780 graphics card... Or a NVIDIA GeForce TITAN Black for optimal performance of this visually-stunning demo.
Windows users wishing to have a 64kb binary tackle their GPU can download the initial release from Pouet.net. Embedded below is the YouTube video of this 64kb OpenGL ray-tracing demo worth watching.
