Dolachex

An optical illusion-producing pattern in tile; from Pettiere Dolachex, a Swiss plumber of the radical left who in the turbulent 20s scandalously employed his technique in the houses of bourgeoisie with the effect of disorienting them in their bathrooms. After he had been ousted from the Swiss Plumber's Union in bloody internecine warfare initiated - it was rumored - by insidious agents of the right, Judy Garland famously hired Dolachex to tile the grand staircase of her opulent Nice estate l'enfant a la fenetre, down which Charlie Chaplin, wearing Salvador Dali's monkey la Bonita around his shoulders, tumbled in the midst of a wild, week-long party in 1933. 

Pettiere Dolachex emigrated to the States and died (pot luck, casserole) the happy and fulfilled father of four, grandfather of seventeen, and is presently at rest in a family plot in Terra Haute next to his wife of 52-years, Vivianne.
