The other day I was clicking around on the interwebs, and found cubeecraft.com. You can download a pattern for a cubic version of your favourite character, print it out (on thicker paper), cut all the lines and then put it together, no glue or tape required. Yesterday I decided to try it out with two of my favourite characters: Sam & Max. It takes about half an hour to an hour per character and the directions for putting it together are quite self-explanatory.
Yes, I realise I have no life right now. This will change, as I’ve set up my own freelance business and my first job starts in June. Glee! ^_^
