I use Stumble Upon which finds random websites to show me based on the interests I selected. I find so many random cool sites this way that I want to share! (I should add: Rio_Kohitsuji told me she got a virus from Stumble Upon once a few years ago. I've been fine butttt it's worth mentioning.)
Ok, so here's the cool site for now:
http://public.research.att.com/~ttsweb/tts/demo.php
It's AT&T Labs Text-to-Speech Demo. Yes, that doesn't sound that exciting. However, I typed one of my favorite Kappa songs into it (Oh Pat), and she "sang" it to me. Ahahahah so much fun!k
ETA: It can swear, and it also speaks in different accents and languages (Spanish, French, and German).
