Tandem Rowing Recumbent Bike

If you love bikes of all kinds, like moi, then you'll get a kick out of this crazy looking bike. It's about as original as they come and would exercise a whole different set of muscles.
Instead of pedaling it, the users row it like a boat or rowing machine. Each person's propulsion system works separately so they can be in different gears and even row w/ a different cadence.
Another benefit: One person can see where they're going and another can see where they've been. If I had more room in my garage, I'd snag this bike in a heartbeat.
I wonder how it does on hills?
There's a great video of how it operates. You can find it by copying the title of this blogpost then going to Youtube and copying it in the search field.
