A series of glass sculptures named for these structures, like Triangular Solid with Circular Cut-Outs, characteristically use two-way mirrors and were created by Dan Graham. In Brussels’s Jubelpark, a building of this type designed like a classical Greek temple houses Jef Lambeaux’s relief The Human Passions.
