Wildlab.com's Test Rides iPhone app is geared to help you match your body to a bicycle of appropriate size. After photographing yourself in the specific position seen above, you then mark your joint locations on-screen, enter the dimensions of a bicycle, and the app tells you whether it's a good fit or not.

We're excited by the human features potential of this app not just for bicycles, but for furniture and workstation design. While it probably won't replace the classic Human Dimension and Interior Space designer's bible anytime soon, with a few tweaks this program could quickly give you vital dimensions of people reaching for cabinets, ascending stairs, slouching into unfocused unconsciousness, et cetera.

Guys and gals at Wildlab, if you're reading, check out this book!
