Here’s the weird-download-of-the-day: Subliminal Message lets you create custom subliminal text or image blipverts that will flash up on your screen - so fast you can hardly see them - at user-defined intervals.
Just why would you want that to happen? Good question. Let me know if you have a good answer for it.
Still, at least you now know that in the event that you ever need to have something subliminally flashed in your face every 20 minutes, there’s a tool out there that will help you do it. And take note:
Because of its perceived power and influence at the subliminal level, this effect is not allowed in TV advertisements in many countries.
Power. Influence. Not many apps offer you that.
