Now all is running well, a bit shakey and noisey but the graphics look good, time to create some proper images instead of test patterns. I looked online for iconic images using only primary colour, found Superman 'S' symbol, I also grabbed the Hack-a-day symbol. In Gimp I reduced the images down to the 8 colours I can display and reduced the height to 32 pixels, after much editing I had versions I was happy with. Gimp will export images as 'C source code' and because this is a text file I can edit the values in a text editor using search and replace. I spent a few hours doing this just to realise that I was creating array declarations of pixel ROWS, what I need was array declarations of COLUMNS, grrrr. A few hours later I had it working and it look awesome!!

Not happy with displaying one image I made some small modification so it would do a slide show, worked perfectly, actually better than I expected. The change from one image to the next was instant so I changed the display pereiod of each to 100 milliseconds and I was animating, lets fo an animation. I found a simple anumation of a flapping bird silouette, converted it to 8 images and presto, animation, it looks really good!.
