I know the SVP of the power equipment company at ABB and sent him a link to this thread. I think it is fantastic work. I suggested maybe they look at them for an article in the employee magazines. I have no idea if anything will come of it.
It is often a mistake to turn a hobby into a job (actually, is is seldom anything but a mistake to do so) but I am certain that, well-marketed, you could sell these for some very pretty pennies, Trainman 2001. They are just fantastic. But if it were me, I wouldn't, just make them.
