Oekaki is the term used for a type of BBS
in which each post is actually a wonderful piece of artwork
which fellow users will leave comments. Oekaki boards are mainly found on anime fansites
, but I have seen some for American cartoons, such as Invader Zim
, and also other fandoms with a large fanart
There are a variety of paint programs in use on Oekaki boards, but the most common seem to be a very simplified program with most of the functions of Windows Paint and Painter, a program with a few different sorts of brushes and sometimes features two layers. All of the artwork is done with either your mouse or a tablet, if you're lucky enough to possess one. The things people have done with just a mouse are quite impressive though, and I can't even tell some oekaki paintings done with a tablet from art that was scanned and painted in Photoshop.
