Feature Request - Canvas/Sketchpad

Would be a really great feature if we could have a canvas channel with some basic ms-paint style binary drawing tools and color palette, a lot of people on servers draw in their spare time and it makes for a really fun way to spend some time interacting with people on the server, would be great if permissions could be set for layers or the ability to draw to allow for events or even drawing flashy looking rooms that make reading server rules a more enjoyable experience for people.
