This is a first video result. I spent a lot of time debugging a mistake in the VHDL code. The video shows 50 blobs moving in HD resolution double buffering. I haven't yet implemented the palettes then it's grayscale. At every frame I do a clear screen. When the loading from flash will be available, instead of doing a clear screen, it will be possible to load a background.

I'm very happy with this first result :-)
