[Moping mode on] Oh, all right . . .
Seriously, though, that's kinda how I roll (see what I did there? ) -- outrageous ideas float up and grab my attention, reluctantly get tabled for the moment, then sometimes come roaring back later as the opportunity (and developing skill set!) permits! For instance, I've always been intrigued by the various auto and truck animation systems, but my limited real estate (only 8X8) has kept me from jumping in. I even looked seriously at a 3D printed alternative before restoring the potential project to the mental shelf.
However, if I converted the McDonalds peg-driven system to a magnet-driven system like Magnorail (likely all that'd be needed is to just trim the peg down and attach a magnet), and arranged for the car track to end at the McD entrance, it might be possible to have a car roll off the Magnorail track, be 'caught' by the magnet on the McD track, and be drawn around the drive-thru (maybe even initiated by a photocell). Still have to work out how to decouple the vehicle from the McD's track and get it back on the Magnorail loop, but . . .
