Andre Kole is one of today's top magical innovators and performers. He has created many illusions such as the Spike Through Balloon, Squeeze Box, Table of Death, Head Mover, Vanishing Feet and many others. When I emailed about creativity, this is how he responded…
Different means of inspiration work for different people. My inspiration often comes from what I have created in the past.
Jim Steinmeyer is the most creative magician I know and he told me that his creative ideas come as a result of studying the history of magic and the creators of magic's past. So if this works for you there is certainly nothing wrong with it.
