There is something new in Java 1.4 to help called VolatileImage. You
build your images in the hardware video regen buffer. Then when you
blast them to the screen they go instantaneously, since the 128 bit
bit/blt video hardware moves it wihout having to cross the
blood-brain boundary of the video hardware memory buffer.

It is like double buffering, but faster and trickier.

Cool! That should take care of that part of the problem, then.
