Kickstarter Campaign to fund batch production of a Bicycle Movement Alert

So if I move a locked up bike fractionally, say 20cm, to allow me to lock to the other side of a rack, will someone come bowling out of a pub to knock me out?

the BMA activating cyclist - depending on movement sensitivity notification preferences - would very likely be notified (as i'd expect most cyclists to want to be notified about a 20cm move!), so would then be able to peer over their shoulder, or gain a line-of-sight such that they could see what's going on with their beloved bicycle; investigating further where necessary, if your movements looked suspicious!

..perhaps then sparking conversation with somebody who might also see the benefit of having a BMA!!
