The Penrose triangle enamel pin in all its minimal, illusion-y goodness (...sort of minimal? This is V2 on this design and actually has a lot more detail than the V1 -- still the same clean form factor and outer dimensions, though!)

Penrose Tri fact: Oscar Reutersvärd (an artist from Sweden) is popularly known as the first person to create the basic form of this triangle (way back in 1934).
