This program is truly beautiful. Initially I had problems because my video card was not doing 3d hardware acceleration, but I fixed that for the nVidia Quadro FX Go1000 by downloading the Linux driver from
and following their instructions. There is a little utility called glxgears that shows your fps, I was at 400, now at 6000 after installing the new driver.

How can we contribute? Some free software offers a paypal account to send a token of support...

Kind regards, Bien Fait!
