What would happen if I tossed it in the washer (on a cold programme)? Is there another way to get old deep mud (I hope! 😬) stains out of this unknown synthetic fabric?
Where else should I ask?

This is likely a very niche request, but perhaps there's a genius here with the answer - or can point me to a better place to ask.

If I want it to look like a web page is loading an interlaced gif over an old modem connection, would there exist some tool to convert a given static image to an animated gif (preferably downsampled to 256 colours)?

You know, the one where it starts off as one giant coloured block which then gets progressively segmented into thinner lines with more detail as each interlaced line is received...

From my understanding, (a) the brain has no nerves, which is why you can talk to people while doing brain surgery on them; and (b) headache is caused by blood vessels constricting. Now, I am unsure whether migraines are also caused by blood vessels constricting, but in any case - what is it that is doing the sensing of this pain? Or is it a(nother) case of the brain just making shit up because it hates me?
