The software asks you to think of a 2-digit number - either remember it or write it down. Click on Next. The software asks you to add the two digits together and subtract them from the original number. Click on Next. You are then faced with a page of symbols from 1 to 49, and asked to look for 10 seconds at the one that corresponds to the number you computed. After 10 seconds, that symbol appears on the screen much larger for a few seconds while an evil cackle is heard.
I ran through it several times, and it worked each time: I clicked through Next twice rapidly without doing the figuring and a symbol appeared that did not correspond in any way to the symbol I had fixed my eyes on. (I also checked to make sure I wasn't absently using the mouse as a pointer.) It's very neat, and I have no idea how it works.
