It has to with my sig. as a joke I left the UHF channel that on older tvs that you can tune to pick up cell phones b/c of the perceptual effect of white typing on black. SO that if you read and then look for where the channel should be listed, youll see a black line of a different shade where it should be, like something is blocking you from seeing it with an illusory black line. It goes along with the theme of the sig. which most wont get anyhow. If you try to highlight that wavering blackline that is produced by the illusion it wont let you. So then they might see that I listed the channel as my location. Only a couple people have gotten it and its just a silly thing I did b/c I was bored.
Just something that has to do with how the white typing on black illusion in a sensory and perception course in Univ. just for fun, I used it, you have to read it all the lettering before for the illusion to be seen
