Animatronic ant

I've just watched a lovely little movie called Africa United, the story of a boy DuDu and his journey to the South African World Cupwhich includes some fantastic animated scenes. The animation uses very low tech methods such as simple puppetes but in a sophisticated way. An ant, based on a simple African child's push toy caught my eye and I've attempted to recreate it's mechanism with the plan of developing my own ant creature (probably in a steampunk style).
Below is a video of the ant I've made today out of card. It's still very rough but woks well. Also a short film on the making of the puppets for Africa United.
