My project for the Cool LED Display has additional constraints.

 

Friends have asked me to help with a competition piece for their sons nursery... The competition is aimed at the parents.

 

They have been tasked with making a Christmas decoration from a toilet roll tube.

 

They want to make an Elf house and have asked if I could produce them a simple light to be placed inside so that it looks like the lights are on through the window...

 

I feel we can do better than just a simple light.

 

Introducing the first proto type...

I decided I wanted lights that flashed like a Christmas tree and also an elf to wave in the window.
