Nice design/idea ! really impressive!
Maybe u could use the same police for dynamic numbers (fps, cycles....) as for the rest of the flash
And also display the average fps in the end, with dynamics included.
Ah also u could fade in or fade out the expanding circles in the dynamics
Nah u know what? Make an updating average of fps in a liquid bar, with 3 levels fixed on the bar (low, medium, high) sothat the viewer can actually see the progress of his fps, and position his performance inbetween the levels. Liquid start high (average including some fixed high numbers in beginning) and then dropping , converging , then u add dynamics and it drops a lil bit more... to converge in the final number :)
Well just an idea :D
