On the Terragen Friends list we have been discussing Jaffa Cakes.
Angela O'Donoghue kindly made a terrain file from a Jaffa Cake for us, and these are my results.

The second one has some unusual colors because Jaffa Cakes are orange cakes coated with chocolate.
I decided that I would make a molten pool of chocolate trying to engulf the orange, with the orange trying to escape.
