I made a portal 2 wheatley clock last year around christmas time. Here is the finished product and how i made it... more or less. i originally posted on different blog but it didn't take off well .. here's the link to the original detailed procedure. I apparently dont know how to upload images.. everything is in reverse order from what I posted . sorry if thats confusing... p.s took me about 5 days to make because i had to wait for the paper mache to set
