Thanks for visiting my site and for all the comments and suggestions. I don't take criticism personally, so I appreciate the honest feedback. I think the contrast probably was a bit light, so I tried to tweak it a bit without losing the spirit of the site. To address a couple points:
Gojomo - I was thinking the same thing about there being an app running in the background that records taps and swipes. That would be pretty cool.
Pyre - This study wasn't meant to be more of a brief survey than a comprehensive study. The Safari image was just light browsing and no typing. If you use any two apps long enough and the smudges they leave behind will look similar, so I limited the amount of time I used each app. I would like to pursue this further and dig a little deeper though, and a few people have suggested other apps to try.
