Artist Antoinette J. Citizen has put together a room making me wish I could be a kid all over again. Called "Landscape," it's a pretty faithful recreation of what a level from Nintendo's iconic Mario series of video games would look like if brought to life, complete with question-marked boxes that ba-bing! when you bump them (or, in this case, press a little button on the underside of the box). Painted-on pipes and pixelated clouds flesh out the rest of the scene. Ms. Citizen should really think about going into the wallpaper business.
