You can now access the site via the alternative URL:
Not that the site stores any user data, but this (in theory) means that any data you post for rendering using the various tools can't be observed or modified by malicious network denizens thanks to end-to-end encryption. And if someone hijacks the site you'll get a certificate warning.
This may not work in really, really old operating systems like Windows XP, so I'm not going to redirect http requests to https for a bit. On the flip side, modern browsers are pretty strict about trusted sites including non-trusted content, so some random stuff may fail, so please give it a whirl and let me know if you see any glitches.
