The Demolition Clock, a very steampunk clock indeed, made from a WWII 'Demolition Tester' used for verifying the cabling on explosive charges before detonation, a very unusual object to start with. Featuring the very robust and reliable IN-8-2 tubes, the orange Neon glow reflects beautifully of the polished brass tube surround, bearing the clocks name.
The Clock is interactive, the front controls on the original equipment activate various features. If you turn one of knobs into the 'Fusion' position, then this coil starts to strobe.
The horn on top also contains a light source - selectable from yet another front panel control, and by chance I noted you can turn the horn round and it projects a pattern onto the wall.
