The Corpus Clock and The ChronophageSeptember 21, 2008
A $1 million mechanical clock featuring a massive time-eating grasshopper made its debut at the University of Cambridge Friday, and famed cosmologist Stephen Hawking was on site to introduce the strange and provocative timepiece.
The Corpus Clock has no hands or digital numerals, but instead features slits cut into its gold-plated face. As the escape wheel moves, darting blue LED lights behind the openings pause at the correct hour, minute, and second.
