There aren't a lot of products where, after buying them, I think, "man, I wish I thought of that," but this is definitely one of them! I've actually thought about doing something similar using a whiteboard, but never could figure out the best control method, but Alan Rorrison was able to figure out a solution. This probably could have been available as a digital download (for most magicians), but the material that's provided gives you more than enough of the basic materials you need to get started. The amount of material provided makes this a great value for the money.

Additionally, I'd like to commend Sans mind on their summary image (I think it's very brief at the end of the promo video). I'd say the skill level is pretty accurate. Audience management is subject to the experience of the performer, but is pretty accurate for the average magician; the performance angle, of course, is dependent on the audience management. Magicians experienced in audience management might be able to get away with a bit more than 180 degrees.

Sansmind really no comments not my type of magic and not worth the price

Just got done watching the DVD and man, I wish I would have thought of something like this! The DVD breaks everything down step by step, nothing gets left untold. YES, you can use your own phone (within limitations) obviously, when drawing the picture with a BLACK marker on a BLACK phone just wont work well haha. I kind of freaked out when I opened my DVD to see the gimmick because all I seen is what was there but once I saw it, I could not stop laughing on how well this was put together! Is this a 180 degree performance? YES! The only con I see with this effect is that you will need to practice with it a few times to get the feel of everything. That and being able to use this effect on practically any phone is a go in my book!
