When you are bored you can get on Dsi Paint. It depends on what kind of person you are as to what you should do when you get on though.
If you like to role play then, maybe you'd want to go to one of the four rp chatrooms (Jasper, Brenda, Minco, or Hockfin)and role play.
But if you just like to chat, you might want to go to a general chatroom (Yoshi, Peach, Mario, and Luigi)or message a friend.
On Dsi Paint you can also make your own virtual avatar called a savii. You can put your savii on your profile page. You can go to the savii auction house and buy and sell saviis, savii points, and savii bucks.
Some people like to play games and go for the best high scores. You can also play lots of games(Whack A Skunk, The Maze Of Blogs, Tap Party, OverlorDS, Yortzee,Minco Says, Savii Slots, Snack Time, and DSi Mystery) on Dsi Paint.
Lots of people I know like to draw.If you are one of those people, you'll like this. You can draw and submit your artwork on Dsi Paint.
Whatever you like to do, Dsi Paint will take care of it, wheather you like playing games or drawing or even just chatting.
