How should it be posed in the file ? when I copy and paste it it gets 
errors from the start.

As for machine it has more than enough for happy 3d 2d computer art 
stuff. But the game engine is just laughable.. ha ha hah hhah ha . The 
blocks fall to the ground and just sit there for a minute 'then'! 
deside to bounce around! It is silly it is like they are takeing there 
time to think about what to do next.

:D
