With PK-Ink App, you can magically move permanent ink drawn on your mobile screen! Key Features • The spectator chooses the exact spot where the ink will appear. • The spectator can select from a variety of marker colors or designs — or you can upload your own drawings. • Move the drawing without touching the phone, using remote control or advanced hand-gesture recognition. Multiple gesture options included: pinch, index finger pointing, open-hand (5 fingers), and more — all highly reliable. • Multiple powerful finales: the spectator will be unable to erase the ink they just saw move. You start clean and end clean. • No internet connection required (unless you use integrations). • Integrate your favorite magic apps with an Ouija-style effect: Imagine the spectator searching for a word in apps like Inject or Elips, and the ink begins to move toward each letter or number — triggered by hand gestures, volume buttons, or fully automatic mode, gliding smoothly across the entire alphabet. Use this as a paranormal illusion with the built-in video animation feature, or as a psychic/magical effect by moving the ink across any Ouija board image you’ve downloaded. • Video instructions available in English and Spanish. • Extremely easy to use — no complex setup or configuration required.
