Hi there, ((FOUND THIS ON THERE FOURMS))
Just thought I would clear some things up. The video itself really isn't hiding anything, if you read the description, that is EXACTLY what the audience sees. With the included presentation one spectator is seemingly able to think of ANY song while the other spectator hears it. This effect has been in the works for about a year now, and the great thing about it is that it works WORLDWIDE; whether you are in Thailand, Italy, or the US, it is made to work internationally. The equipment is home made yet very durable. I know a number of professionals such as Oz Pearlman that perform this effect in close-up environments as well as on stage. The effect itself was primarily designed for stage but can very easily be adapted for close up situations. I put a lot of work into this, read the description it is, like I said before, exactly what the audience sees. It is simple, nothing complicated to do, and once you have the presentation(s) down pat you will be performing miracles.
Very Truly,
Alex Vante
