Maybe, Someday

I cannot figure out how to embed audio player into this stupid thing. Eff you, Blogger. In case anybody feels like shoving this in my face, I've read it. Seven times. I'm going to try reading the 'video' topic to see if it helps any, but I sincerely doubt that I will ask on any forum. I'm too lazy/shy/lazy. If it works, I will... Erm... I will do another podcast. With a topic.
On a completely unrelated note, has anybody ever heard of a monocycle before? It's not a unicycle, if that's what you're thinking. Here's a pic.
If you've paid attention to pretty much any other post on here, you will know I am now totally bent on making one of these.
Theoretically, it shouldn't be hard. I just need to learn about bicycles. And locate a large enough outer wheel. And all the other things one needs to build some sort of cycling device.
This could be harder than I thought. But on the other hand, I'll probably be the only on in Washington--or the Northwest--to own one, should I succeed. Which I won't. First off, where do you even get the stuff for that, specifically, a durable wheel at least six feet in diameter?
... And apparently, preferably a gyroscope. What in holy hell's name is a gyroscope?
