The Triangle tray

An equilateral triangle of tiles that point up and down in turn. Comes in an 8-row and a 12-row tray.

• Neighboring tiles always point opposite ways: one up, one down.
• Eight colors, from sky blue and lavender to navy and black.
• Pictures and geometric patterns, plus app originals for the 12-row tray.
