3D game on OLPC laptop XO-1
(sorry for video quality as been recorded with webcam)
UPDATE: You can download experimental .xo packagae for installation on XO-1 and XO1.5 laptop models here http://activities.sugarlabs.org/fr/sugar/addon/4574
It is based on a heavily modified Quake1 game, work both on XO-1 and XO-1.5 models as well as any GNU\Linux x86 without the use of OpenGL 3D acceleration (don't need 3D card/chip) which mean it can be used on very old computer and can be ported to tablets or smart phones .
This is just a proof of concept and not the complete game
you can download a zip of the activity here: http://www.4shared.com/zip/Ew1DrJbF/activity.html
