Think inside the (very small) box!

This challenge is a simple one - create a puzzle based on a small square grid. Grids must be 2x2, 3x3, 4x4, or 5x5 in size - no bigger!

The grid itself does not have to be small in physical size - for example, you may wish to fill each square with an image or a sentence; this is fine. The challenge is to restrict yourself to a small number of cells.

Small pen-and-paper puzzles, crosswords, wordsearches, Boggle grids, and grid-deduction puzzles are (of course) welcome, as are connecting walls - but by no means are these the only ways to use small grids and make an interesting puzzle... You may need to think outside (or is that inside?!) the box!
