Strange tower

A huge dark tower with rusted metal girderwork and sinister ancient machinery built into the stonework.
The model itself is 3 ft high, and covered in a vast array of old model kit parts etc. The stone detailing on the main tower section is actually made of breakfast cereals - rice bubbles and corn flakes. It's a time consuming method, but gives fantastic looking texture. And yet we're usually told from an early age, not to play with our food... :-)
