From Custom Solutions of Maryland:
Subliminal Message Pro (SMP) lets you explore the idea of subliminal messages. Messages up to 80 characters are flashed in the middle of your display. The SMP Control Panel lets you set the period between flashes, the font size and color, font darkness, choice of message selection (in list order or at random), possibility of reverse spelling, and automatic minimize of Control Panel upon launch. A shortcut is provided to Pause/Continue flashes. Five message categories with five messages each are provided to help you understand how the program works; you can replace these with your own categories and messages. Categories and messages may include Latin, Japanese, Spanish, French, German, Greek, Korean, Cirillic, Hebrew, Russian, Afrikaans, Polish, etc.characters. Control Panel settings and location and Message Table information are saved between sessions. SMP is $20 shareware. You can try SMP in Demo for ten minutes per launch, after which time the application closes. Registration removes this limitation.
