There's an interesting, wild article on the origin of confetti from ancient Greece at CABINET here. There's also a neat little glimpse at pastry invention in Europe and its history. There's a longer look at Carnival in Trinidad here.
There's an interesting look at the history of colors and dyes like cyan blue and indigo. There's also a little history of the three-legged wheel, the three bent legs connected together, called the triskelion--it's a symbol of the island of Sicily off Italy and of the Isle of Man by England and Ireland. It's sometimes depicted with spirals instead of clearly defined human legs.
There's a neat look at festivals that include oranges and throwing them here, covering rituals in France, Belgium and Italy. There is also a look at the very eerie secret tunnels and rainbow hued rooms of the Italian new age 1970s commune Damanhur community in Piedmont near Turin--un-relatedly there is a real city called Damanhur in Egypt.
There is an complex, almost Derridean look at mazes and labyrinths as well.
