As it turns out, these are real sites that got scraped. http://www.dpgraph.com/index.html works, and it looks like the software is free to download now. I’m too much of a chicken to try though...

A lot of these sites don't support HTTPS, so they can't be iframed without being mirrored

I can't recall the last time I made a noise opening a web page.

This one sounded somewhere between a hiccup and vomiting. Kind of a 'Hulp!'
