How to see it
Solo (subtle) — Dark room. Hold phone screen-out at arm's length, eyes locked forward. On GO, sweep horizontally fast across your peripheral vision. You'll catch a glowing afterimage of the word.
With a friend (full effect)
- Friend opens iPhone Camera → Photo mode, makes sure
Live Photo is ON (top icon, concentric circles)
- You stand 2-3 feet away, screen facing them. Lights off.
- You tap Inscribe. On the GO flash, sweep your arm fast & smooth.
- Friend taps the shutter mid-sweep.
- Friend opens the photo in Photos, swipes up, taps Long Exposure.
- Your word is now floating in their photo, glowing, in real space.
