These Hasbro-licenced kits from PDP will cunningly disguise your Nintendo DS as a Transformers character.

Launched as the new movie, "Revenge of the Fallen", plays out in cinemas, Autobot and Decepticon supporters can choose between a Bumblebee- or Megatron-themed stylus and armour.

The kits are on sale now in the US with the stylus on sale for $12.99 or bundled with its respective armour for $19.99.
