The demo is for windows only and I think closed source but it runs well with
the most recent amdvlk. On radv it crashes.
You can get it here: <a href="http://www.pouet.net/prod.php?which=76464">http://www.pouet.net/prod.php?which=76464</a>
Make a 64 bit wine prefix, run wine64 Tangrams.exe, click demo and it
immediately crashes with this message:
