"Habitat vignettes" are a very popular method (just do a Google image search) of making little displays to showcase individual minifigures. Every year when LEGO releases a set of Collectible Minifigures, a lot of people around the world find cool and creative ways to display them in a small "room" themed to the figure.
With a set size (12x12 studs in area, 8 bricks in total height), it is easy to make one or more and assemble them together into a "wall" of little rooms. This is what we did in my club last year, with multiple vignettes on a single table as part of a group display.
My first was a lion cage to show off the Zookeeper minifigure (Series 5). It was fun trying to figure out ways of securing the vegetation at different angles to give a more "overgrown" look to the background.
