I really was impressed with the simplicity that was put into this. Mark Presley really took this to a hole new art form. When I first received the butterfly effect I didn't know what to think. It has a special housing system that holds the butterfly. I thought after opening it that it would be another magic effect that would end up on the shelf, collecting dust. One day I decided to put in the dvd and I was impressed with all the moves Presley came up with. Like I said I played around with it without looking at the DVD or instructions so when I saw all the moves Presley came up with I was even more impressed. You do have to be careful of lighting and background. I decided to use it in one of my shows and I got a nice response. The dvd is very thorough and the instruction booklet is full colored. I'm thinking that many will look at this effect and not see the value almost like I did.
