Chrome users, if your utterance goes over 15 seconds, you may need to close the tab. http://tinyurl.com/chrome-bug-679437
u/cantelope

very clever :)... btw, which dweet of mine crashed your lappy? ...just curious
u/joeytwiddle

This is the one, it can reliably overheat my CPU: https://www.dwitter.net/d/2355 I think it's due to the size of the large squares. I have had to adjust the cooling thresholds!
u/cantelope

:/ sorry about that.
u/joeytwiddle

No worries Cantelope. Wow Mac has a lot of voices. The "Cello" voice is pretty funny! https://codesandbox.io/s/vq48b #audio #speech
