The Steampunk Workshop blogpost covering this project is entitled 'Truly Awesome Steampunk Mouse'. I'd agree with that. Shown in the thumbnail there is the USB plug. Click on it to see the mouse itself. Or click here.

The SnowBlog is one of the oldest publishing blogs, started in 2003, and it's been through various content management systems over the years. A 2005 techno-blunder meant we lost the early years, but the archives you're reading now go all the way back to 2005.
Many of the older posts in our blog archive suffer from link rot. Apologies if you see missing links and images: let us know if you'd like us to find any in particular.
