I just committed a different fix on my branch. I added RigidBlend
method to matrix which uses quaternion slerp for rotation and linear
interpolation for position. it probably breaks scaling as I simply
ignore it for now. I am going to test / fix that the next thing, maybe
tomorrow on a train.

great, thanks. i was taking turns with someone doing blurry videos,
which went well together with my brightly colored sharp shapes. pity
we couldn't project one over the other. Many people asked me after
(and during) what software I used and I gave away fluxus URLs and
showed them GLEditor :-) They would then ask "do you have to learn
lisp to VJ with a joystick?".

The worms didn't make it in time for the gig though :( Will have to
look for a next one.
