For a bit of a laugh I wrote a Conway's Game of Life in Excel using cells as pixels. I could get quite smooth animation up to a screen size of around 200x200 cells. The main bottleneck was the need to check every cell in the grid, every generation, which quickly becomes hard for VBA to do smoothly. It was fun however to see Excel doing animation.
