I just recently purchased the Richard Sanders show DVD set and was amazed to find out the stickman routine he performs is virtually the same as a routine I came up with myself vitually all the same moves, same sequence with only a small difference in presentation, I was quite gutted as I thought I'd got something original.
I would be interested to know of anyone else out there that came up with something which they thought was original to them only to find out they had in fact reinvented an effect. To finish on a good note the DVD set is very good and I recommend them highly.
