I don't think we have a Android apps thread yet, so here is one if you want one.
I've just been giving LHSee (all about the LHC, see?) a spin on my tablet, it's quite educational and a little bit fun too. I haven't had a chance to work through all of it yet, but I'm hoping there's an Easter Egg where a collision event generates a black hole and everything on-screen gets swallowed up. Or have I just got too much of a sick sense of humour?*
*You don't need to answer that.
