Some four years ago, I wrote in Fun with Markov chains about T9 collisions (the fact that predictive text input on mobile phones sometimes turns out interesting alternatives).
Last night I was contacted by someone who'd found the original post and was looking for a T9 collision translation (i.e. translating a T9 pair in language 1 to a T9 pair in language 2, trying to maintain the meaning).
That's still in progress, as you can imagine. I did find a nice new (half-)Dutch pair, though: godfather = infecties :-)
