Orbit Wheels are wheels that you put your feet through and then skate around sideways. They cost a not-too-bad $145 and mine just arrived. I'm going to take them for a spin and I'll give you the report when I'm back.
UPDATE: They were surprisingly fun. Unfortunately they were also unsurprisingly made fun of. A whole bus of middle-schoolers called me names so mean I can't repeat them here. A high-schooler purposefully tripped me and then tried to burn me with his cigarette. Then when I got home my dad told me I was no son of his and punched me in the eye. Verdict: Crying.
