I realise I haven't posted anything here for some time, so here's something I made to amuse my musical friends on Facebook (with some success). The concept is taken from a Will Heath Robinson drawing I saw in an exhibition not long ago. I could have bought the original (if I had lots of money) but I decided to steal emulate the Master's idea instead.
The original image, on the left, I found on the internet; it's not very big, and so my piece isn't either.
