Boxes piled into towers and shapes that your eye swears are solid until you follow an edge round and it doesn't add up. Fifteen stacks and five impossible triangles, twenty starters built out of clean flat faces.
These are the ones where shading does the heavy lifting. Put your lightest tone on the tops and step the two side faces darker, and the whole page lifts off the paper. Markers, pencils, a single gray, it hardly matters: pick three tones and the blocks turn solid in front of you.
