This is a time-sensitive, one day only link. But if you're online - er, as you must be if you're reading this - go take a quick look at search engine Google, where they've recreated their distinctive logo in Braille to celebrate the birthday of its creator, Louis Braille. Sadly, of course, it doesn't work in quite the same way as actual raised dots, as I can confirm after trying to run my fingers over the screen.
