More than a principle, more than an effect, it's a tool that will never leave you!
I used to love using a Bakner forcing on the Disney Channel (among others), published in his conference notes on magic for children... a few years ago! Here, with Nulle Part Ailleurs, it's formidable once again.
What's truly astonishing is the distance between mathematical simplicity and the totally random feeling of the mixtures and the viewer's choice. The variations on offer are obviously brilliant, and above all inspiring. You'll be able to create an effect you'll see nowhere else!
It's up to you!
