Mountebank – The Peek Utility Hiding in Plain Sight
Mountebank by Mark Lemon is a precision-made peek device built into what looks like a perfectly ordinary black credit card. No electronics, no apps, nothing to charge or pair – just a tool you can carry every day and rely on every time.
The secret is a specially manufactured lens made to Mark's own specification. From your side, anything beneath the card is clearly readable. From the spectator's side, the card is completely opaque. Return a billet to the everyday items in your pocket, place them into their hands, and you've already seen exactly what they wrote or drew – while your audience sees nothing at all.
Why a credit card?
Putting a billet back into a wallet just to get a peek has never felt natural – and fewer people carry wallets at all these days. A card, on the other hand, belongs anywhere: on a table in a café or bar, in a formal show, mixed in with coins and cash, used in a bet, or simply sitting there without drawing a second glance.
Far more than a billet peek:
- Access cribs hidden in plain sight
- Combine with electronic peek devices you already own
- Explore handlings using the Steam principle
- Paperclip to a window envelope for an ultra-clean peek
Key Features:
- Directional, performer-only viewing angle
- Completely passive – no electronics, batteries, Bluetooth or apps
- Natural everyday carry
- Instant access to written and drawn information
- Works as a covert crib
- Compatible with existing electronic peek systems
- Suited to both casual and formal performance
