My son is a Tetris fan lately. He’s competing with my friend in South Africa (they’re both playing the same game, and sending boasting screenshots by WhatsApp). He came to me with his laptop (actually mine, I’ve loaned it to him) over the weekend, excited to show me how he’s playing Tetris on the MacBook Air, in emacs …

He doesn’t really appreciate quite what emacs is (or Vim, for that matter), but he definitely loved this version.
What do you think?
