Illuminated climbing wall teaches you how to spell while you fall

This climbing wall / human size LED display called the “DigiGripper”, has a few tricks up its sleeve. If you hold onto an illuminated dot, the dot retreats into the wall causing you to fall on your butt. The longer you hold onto the display, the quicker the letters change and the person who holds onto the display the longest becomes the winner.
