I call it the morg wallpaper app.
You're referring to strange lines and images on your skin surface, that appear and disappear...especially after taking or topically-applying a substance intended to be unpleasant to the morg?
If you choose to keep the app I'll be billing your paypal or visa account.

Take pictures...Yes, I am familiar with it and I do know what it is. I think. Pics are essential.
