Just back from an excellent talk by Tim Hunkin of "Secret life of machines" fame. He started things off with a description of how a telephone works and demonstrated a loudspeaker made from a crisp packet. He then went on to talk about his latest arcade creation "I-Zombie".

This latest game combines a classic optical illusion (Peppers Ghost), carved wooden figures, video screens and some cunning mechanics. The front of the phone as two video screens with animations, instructions and scoring. The control is via a selection of PLCs which Tim like because of their reliability, ease of use and that he can get them cheap of Ebay, And of course given Tim's mischievous nature, there is a twist.
