Remember when the web used to be fun?
In the spirit of that age I made a little website that does a lot of fancy maths and thinking stuff to tell you if you're alive or not.
Enjoy!
New blog post: Transmitting data via ultrasound without any special equipment
Did you know your speakers can play (and your microphone can record) audio at frequencies beyond what most people can hear? They can! And you can use that fact to secretly transmit data!
edit: oops, that had something weird going on with the youtube embed. fixed.

And here we have the noble capybara - the guinea big, if you will - doing a quick under the chin buttercup check to find out if they like butter

Ahh. Friday evening. Drinking gin. Sorting through photos. Trying to work out, in an increasingly exasperated manner, what kind of chameleon is looking at me very suspiciously, when they look different in EVERY SINGLE ONLINE PHOTO 🤷♀️
My information says it's possibly a Parson's Chameleon but if they had others it could be one of them. A funky creature, whatever. If you definitely know what type it is, please let us know in the replies.

Everything in the reptile house was looking at me a little suspiciously. I have no idea why.

But still. ORANGUTAN! 🦧

(I am being serious, someone needs to tell them to change that name right fucking now, and I will go do it. point me at the right people.)
I am now going to channel the serenity of this orangutan, think peaceful thoughts, and head off to sleep. Sweet dreams all 💤

The Zoo Trip Photo Thread
Although I'm sure I will get distracted with scribbling at points, I have a few photos from our trip to Chester Zoo that I just want to post to say LOOK AT THIS BEAUTY, so I am going to stick them together as I sort through 🧵
This is the first. A purple starling and, well, LOOK AT THIS BEAUTY!

The very serious and contemplative white-headed vulture, looking a little like it's wearing a very fetching black feather boa.
Also, don't want to be picky, but it really should be called a pink and blue headed vulture.
