I got an idea tonight: Emacs must have a meme generator. Using a web browser seems so jejune.
After pondering a few minutes and then typing a few hours, here it is. And here’s how it looks in action:
It basically just manipulates an SVG image, so it’s less work than you’d expect.
If you want to play around with it, you need a very fresh Emacs trunk; see this for easy installation instructions. You also need the Impact font from the Microsoft font collection; in Debian it’s installed by saying
apt-get install ttf-mscorefonts-installer
Uhm… I think that’s basically it.
