The engineers in question are not retired. Here's what it says on their web site:

"Tom Baynham and Ben Tyers founded Baynham & Tyers in 2006 following the completion of their Masters degree in Manufacturing Engineering, at Cambridge University.

"Baynham & Tyers is no longer an active company, as Ben and Tom are heavily involved in exciting new projects."

Here's another amusing (but weird!) little interactive program I found at the same German web site (chilloutzone.de): Mauszeigerüberlebenstraining (Mouse survival training) depicts a helpless George Bush falling through space and bouncing off various bubbles. If he gets stuck, use your mouse to give him a nudge. Or just grab him and give him a good shake.
