Martin pointed me in the direction of biteycastle, a website full of some great flash animation, here i found the work of Adam Phillips, my favourite parts in particular were 'little foot' and 'the yuyu'



Little foot is full of great characterisations and you feel very differently about each character, theres an obvious bond between big and little foot and an really smug satisfaction to be had when bitey gets knocked down.

Unfortunetly embedding was apparently disabled on this video, but if you follow the link its well worth a look. Though its less character based and more about the narrative of the pursuit, i found it visually stunning, i havnt seen a huge amount of flash animation but that really impressed me especially in his employment of basic principles to give the bitey character an inhuman speed that still seemed belivable.
