I heard part of a report about a firm that is developing glasses that will flash information to you throughout the day - the subconcious picks it up and it dramatically improves your memory. I know this comes as no surprise to the folks at LSI.

It certainly is an interesting application of one of the stages of the PR process.

I saw that too. The guys on Slashdot were all like "this subliminal messaging stuff is absolutely bogus." I laughed at their ignorance.

I did a quick search on dogpile and it looks like the folks at MIT are involved.
