hey ya'll,

...motion blurring is a very high priority for me atm :-)  
Unfortunately, there isn't exactly an easy way :-\  The traditional way 
is to cheat and use the accumulation buffer:  ya render to this buffer 
several frames with each slightly lighter, then pop out the 
result...this doesn't give a directional blur, tho, and also it so 
happens that OSX has a software implementation of this buffer, so it's 

...the better way is still in the future, and involves vertex &/or 
fragment programs along with pBuffers...there's plenty about this on 
the web, but it's just not do-able in GEM atm...soon, perhaps?
