Yet Another Pummer.......

I'm getting quite a good supply of project housings,some ready bought and others made by myself.They are waiting for something to make them complete,and so can sit for some time on the shelf.
This one had not such a long wait:the housing is a tall rectangle made form Aluminium and wood,what made it complete was the glass pyramid I bought not too long ago.The name is not hard to guess then:The Pyramid Pummer,inside the glass is a very bright blue LED and the battery is a 3.6 V lithium-ion one from a mobile phone.
