Thoughts about my next experiment, ukulele arduino and merapi

I’m thinking about a new experiment.
Here’s the thing, I love playing Ukulele. Once a Month we organize a playalong.
There are people who never played an instrument before and others that are regulars.
Together with my Friend Marcel, creator of ukulele.nl has made a really nice chordfinder
I will be making a version 2.

Here’s the though: what if ?:
I could build a Ukulele that shows the fingering of the chords ON THE UKULELE!
And even have it sync to the chords shown on screen?

What do you think, wouldn’t this be a cool Merpai/Arduino/Ukulele project?
