Ok, this is the idea:
I maybe don't want to use 15000 pins, but the idea is there.
I have a picture and have reduced the size down to "SMALL!" size but it still has too many colours.
I tried to reduce the colour depth to 4 colours but that made a mess of the picture with the dithering and that stuff.
I have seen it done with LEGO as well at a show I went to recently.
Anyone every done it and could help me work out how to get it working?
