The height of my doing single frame animations was during the 1980s with the early computers, larger pixels and limited numbers of colours – sometimes only two! However, I got hooked on the technique so much that in the early to mid 2000s I started a new series of animations using the same technique but with more powerful computers. My project A to Z never reached completion, but I'm hoping that one day I might use a different generation of computer to finish what I started then.
