Drawing-grid is a fun project where people can create a picture just by clicking cell by cell in a big table. You can easily switch colours to make a real masterpiece. The clicking is not ideal, but the results are sometimes really amazing, especially the ones in the category portraits (new window). The images on all those pages are generated on the fly with Convert & htmldoc when I approve them. I've written a small article about it also on this small sub-site, so check it out. If you have some spare time, create one yourself or vote on the ones you like.
