Anyhoo, I decided to make my own.
He's called Heed.
Step 1: The plan, the tools, the materials
New for 2009! At no extra cost! I have re-drawn the template as a PDF file, including Mykhailo's suggestion for retaining the head. It is now attached to this step.
You can scale it up (or down!), photocopy it or draw a version yourself.
Heed can be made in paper, but will last longer if made of light card. I used the 160gsm that was already in the photocopier at school.
You will need a pair of scissors, plus a sharp knife to cut the slots that make the connections.
When using the knife, cut on either a proper cutting board or a pad of scrap paper to save your work bench.
