“Marc's apps are unbelievable.”
—David Blaine
ISO is a digital solution which enables many analogue effects.
ISO lets you perform miracles using a borrowed phone.
*** You can use ISO for:
- Bill to impossible location
- A book test with ANY printed text (a restaurant menu, a borrowed book, a magazine, etc)
- Pegasus page
- Playing card forces
- Stacked deck effects
...and so much more!
For example... imagine:
- You ask your spectator to borrow a bill, which they place on the table in front of them.
- Using THEIR phone, you openly take a photo of the bill to verify later.
- You crumple the bill into a ball in your hand, and have your spectator hold your wrist.
- You slowly open your hand to show that the bill has now VANISHED!
- The spectator then checks under their bag to find the bill!
- They check the serial number… it MATCHES the photo! It’s the SAME bill!
* Your phone is NEVER in play!
ISO only uses the spectator’s phone during the effect, meaning your phone is never seen.
* Carefully justified in every way
All stages of ISO’s possible effects and routines have been carefully thought through and are justified at each step.
* Works in ANY language
ISO is performable in any language. No text is visible during the effect, and so ISO can be used in any country or region.
* Introducing Serial AR
A new way to use ISO in collaboration with William O'Connell. ISO is now even easier to perform, removing the need to take a photo in advance! (Serial AR requires a one-off, optional in-app purchase. It currently works with GBP, USD, EUR, CAD and HKD)
* Multiple pairing methods
Includes an adaptive peek screen, plus optional printable pairing stickers and NFC tag support.
* Fully customisable
The many included settings, features and modes available let you use ISO for many different effects.
* WikiTest pairing integration
Performing ISO can leave your spectator paired and ready to perform WikiTest at the conclusion of ISO’s effect.
* VERY easy to perform
* NO accomplice used
* NO memory work needed
ISO is for entertainment purposes only.
Please get in touch to discuss video/audio/TV/internet broadcasting of any description of this effect.}
