Mouse-assisted Tea Maker

Inspired by the success of my 'mouse-operated swordfighting puzzle', I entered the PG Tips 'invent a Cuppa contraption' competition with this. Top prize was £10,000, with 50 runners up getting DVDs. I got nothing! I thought it was a pretty good cuppa contraption myself, but I guess they were actually more after proper 'inventions'. Oh well, it was fun to design and draw it anyway!

(I really wanted to put this in the 'technical drawings' section, since that's a much better fit than just 'miscellaneous', but I'm pretty sure it wouldn't fit in with the other stuff there, and also used a lot of Photoshop colouring and typesetting so probably isn't allowed on that count).
