Pretty cool app that does some of the dice rolling for you.

Apart from the proposal I had in the other thread for using a table like this for weapon aiming, that's about all I can think of; there's a couple of Android game-aid apps for Battletech, but I'm not convinced the time saved would exceed the time spent screwing about trying to click the right options on a touchpad. Might help until they got a good grasp of the rules, I guess.
