This was a random thing I did very late at night. It was an idea to improve some cheap coloured globe lights with little LED trees inside.
The project also included a little LED tester/comparer that doubles up as a neat little USB ornament that runs at very low current.

Here's the listing I've just ordered some concave lens LEDs from. They're the type used in Christmas lights for all-round viewing.
