My friend Jerry Michalski sent me this really cool thing:
Aoccdrnig to rscheearch at an Elingsh uinervtisy, it deosn't mttaer in waht oredr the ltteers in a wrod are, olny taht the frist and lsat ltteres are at the rghit pcleas. The rset can be a toatl mses and you can sitll raed it wouthit a porbelm. Tihs is bcuseae we do not raed ervey lteter by ilstef, but the wrod as a wlohe.
This would be a good way to "encrypt" cleartext so that it could not be understood by Internet sniffers! All you need is a Scrambler script. You write a document normally and then your Scrambler mixes up the middles of all the words for you. It is still readable without decryption, but any Net sniffers that may intercept it in transit (via email for example) won't be able to make sense of it at all. Very cool idea...
