I walk by a 7-Eleven everyday and recently I notice the store is promoting a NT$39 sushi roll for breakfast. The poster on the store window shows a sushi roll that is based on a progressive transformation of a rectangle into an ellipse.
I can't help but be reminded of Le Corbusier's St-Pierre at Firminy-Vert. The church was designed in the 60's and completed in 2006. The building's main volume is based on a transformation of a square plan into a hollow conic shell.
