Portal Cake

The cake from the first Portal game. Without the rhubarb, mind.
My portal cake :) Chocolate cake (with fish-shaped crackers inside), covered in chocolate ganache mixed with chocolate chips, gratings, chopped nuts and more fish-shaped crackers, topped off with icing (had no thick pipe-frosting) and glacé cherries. No sedimentary sediment, mind.
The crackers were a basic sugar cookie recipe, and I made the cutter using a drinks can, some pliers and a stapler.
Made for my boyfriend's birthday in June - made it all the way to Download festival intact! Took hours to make. Doubt anyone will want/need instructions but if anyone does want a how-to, I have photos of every step and the recipé I used :)
