Revealed through the ESRB rating website last week, Rock N' Roll Climber has made its debut this week at the Nintendo keynote in its full rock climbing glory.

Using both the Wii Remote and Wii Balance Board, players can act like true rock climbers by using all the parts of their body. As seen in the video above courtesy of Kotaku, you too can see how you can climb walls like Spider-Man.

It may make you look absolutely ridiculous, but it's doing what it's set out to do - make you climb rock walls. This kind of crazy tech demo stuff is just what the WiiWare should really do far more often.
