The Ukelin is one of the strangest instruments ever invented. The name suggests it's a cross between a ukulele and a violin, but it's closer to a zither and a violin. Although rather than being a 'cross' it's actually two instruments stuck together and you're supposed to play them both at the same time. Bowing with one hand and picking with the other.
The instrument was originally a door-to-door salesman scam and it was a very successful one. There are a huge number of these instruments around and you can often find many of them for sale on eBay at a price low enough to make it worth buying just for laughs.
One problem with the ukelin is the strings. If you can buy one with a full complement of strings, do that.
Because it's so hard to play, videos and sound clips of the ukelin are few and far between. This girl sensibly sticks to playing just with the bow.
