On the whole I’m used to seeing one thing pop up in Ross Crawford’s (RoscoHead) photostream: cranes. So spotting a LEGO ukulele there this morning was somewhat of a surprise. Discovering it worked was less of a surprise after the initial shock.
 

To quote Ross:

Realising I’ve never owned a uke, I decided I’d try to make one. But instead of using wood, like any normal person, I decided to use LEGO bricks. Of course, there were some challenges: 1) Shape, 2) Strength, 3) Tuning, 4) Intonation

So, after all that, I ended up with what I like to call an alto ukulele – it is tuned to C-F-A-D (normal ukes are generally tuned to G-C-E-A). I also thought it needed a stand so I can display it on the mantle piece, you can see it poking out the bottom. And I think it really sounds OK, but you can judge for yourself: Puff the Magic Dragon

And for those who missed the link in the quote, here is Ross playing a well known song on his LEGO ukulele.
