And it is claimed that the truncated icosahedron is responsible for the 
"Self-organized breakup of Gondwana":

(nice application, at least...)

I will quote from John Baez, from 
http://math.ucr.edu/home/baez/platonic.html

"Everything sufficiently beautiful is connected to all other beautiful 
things!
 Follow the beauty and you will learn all the coolest stuff.
 The Platonic solids are a nice place to start."



Platonically,
