Yes, I added a f_hypot(x,y) multiplier to the two 'rotation/shear terms' 
to create something more interesting than the square-frame rotating and 
shrinking.

Attaching two more mp4s. The one with the _BW.mp4 suffix removes that 
f_hypot() multiplier.

The one with the _SinCosHyp.mp4 suffix adds a sin() then cos() wrap of 
the f_hypot() multipliers. Done with the thought it might be 
interesting. :-)
