...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?
