Chapter 08. Persistence of Vision


Atop of the Evil Genius’s lair, there is a sign that is holographic in appearance and displays the slowly rotating message that says ‘Hello’. The sign uses a vertical line of multicolor LEDs that rotates rapidly producing a persistence of vision effect. The main purpose of such a display is to help the evil genius to find his way back to the lair after visiting the local bars.

Design your own messages with the message designer here.
