These Colorful Plates Will Remind You of High School GeometryS

Beware if entertaining using these kaleido trays—you could find yourself spending hours placing them into different geometric shapes and arrangements.

They come from the brain of Clara von Zweigbergk, a former graphic designer. They come in more than a dozen shapes and colors, ranging in price from $17-$84. It says they're not actually okay for food use, which severely curbs their cool factor, but you could easily find a ton of other uses for them around the house—including a new party game.
