I think the Hurdy Gurdy is a really interesting instrument. I don't know much about its history but for supposedly being a beggars instrument it's massively complicated. Some of the contemporary compositions that musicians like Guilhem Desq are putting together are just wonderful. Its nature means that you can do a lot of wacky shit with it if you get creative, it's so versatile. Like a medieval synthesizer or something

I would also like to point out musicians like Andrey Vinogradov who do spectacular, but more traditional and simple arrangements.
