Boulder-riding performer Dorothea Ulrich testing the final foot mount.
Performer foot mount in position. The 2×4 system protruding forwards is the skeleton of the mechanism that locks the boulder into the floating tea house.
PA Greg Lookerse and PA Christian Meade designed and fabricated 7 versions of the foot mount, each version slightly better than the previous generation. This is version 4, which featured the better angle. Great work guys.
