Two poles of different lengths balanced simultaneously on the head, as well as some other balancing tricks. This is know as a dual or twin inverted pendulum in control systems engineering. In the first 2 clips I use a long pole that is 4 times the length of the short pole. In the 3rd clip the long pole is only 3 times as long and is more difficult. The poles fit together in sections so that I can pack them in my bag. They're made from a cheap Argos wardrobe. The ball on the end of the long pole is mainly there to make the end more visible. I'm using rubber chair leg feet at the bottom end of the poles. Music is 'Heartbeats' by The Knife.

A video of a performance I did for the Sydney University Engineering Revue. Be warned, this video does feature my naked bottom. It is however, quite hilarious, so that makes it OK!

Getting closer to my goal of 10 seconds. The images at the start from left to right are Enrico Rastelli (1920s), Leon Rabello (1936) and Paolo Bedini (1943). The machine learning shows a genetic algorithm evolving a multi-layer perceptron neural network controller to perform the balance in 2 dimensions. A 2D rigid-body physics engine was used for the simulation. The performance of each trial was assessed based on the time balanced and the average 'uprightness' of the stack over the duration of the balance. http://www.mathworks.co.uk/matlabcentral/fileexchange/36911-machine-learning-balancing-a-stack-of-balls

This is Johan Wellton's most advanced and lavish stage production ever. With special effects, natural phenomenon and the art of engineering he shoots out for a new and unexplored adventure. All inventiveness and experimental curiosity becomes the framework for a story about our dreams, hope and despair. How far are we willing to go to become loved? To understand ourselves? To find context and a meaning in life?/nSee one of the world’s best jugglers in what may be one of the most complex shows about something as simple as life itself./n“It is totally sensational, mind blowing" - Expressen/n“Spellbinding chaos” - Hallandsposten/n“Do not miss it, whatever you do.” - Västerbottens-kuriren/nTour dates and more at: http://www.johanwellton.com/en/for-arrangorer/glitch//nGLITCH was produced 2010-2014 and premiered September 2014./n© copyright Johan Wellton - all rights reserved.

The feeder is "A", the juggler to the feeder's left is "B" and the juggler to the feeder's right is "C". The feeder counts "1 2 3" to make it easier to keep track of where we are in the pattern. On beats 1 and 3, A (the feeder) and B exchange a pass. On beat 2, A and C exchange a pass. On 3, juggler B catches the pass and walks on four count (rotating the positions anti-clockwise). 1. "iC": The manipulator (M) intercepts the pass from A to C. The juggler who was C is the new manipulator, and reads from the manipulator line. 2. "cA": The manipulator substitutes a _pass_ from A to B. 3. "sC": The manipulator substitutes a _self_ from C (to C). The passes _from_ the feeder are not manipulated, the feeder does only normal pass throws to B, C, B
