A 1 on 1 conversion from Glen Murphy's "Fluid" example in Processing. No flash specific optimalisations or any optimalisations at all yet. Did add a blur filter, to smooth the low-res (15x15 grid). Doesn't come close to the speed of Processing's use of the JVM, but still. This is pushing AS to the max, but the FVM (Flash Virtual Machine) rendering engine is not the one causing the problem.
