To join this room you must draw 100 hands (past hands count, skeleton hands count). Good luck. (Some people will be exceptions but they wont have a star by their names)
This room is used for experimenting, practicing technical skills etc. Pushing the limits of what you think you can make. Backgrounds characters, studies, machines, etc. You don't have to put in 100% into your doodles but try and push beyond every now and then.
