Its taken a while, but my virtual realtime Meccano model of the Eiffel Tower can now be downloaded from here. I think that I've stretched the capabilities of 3Impact (as well as my own) in the process. But its been rewarding, nonetheless.
Its cost me a couple more grey hairs and a few swear words, but I've finally got all the gears turning correctly. I've still to add the elevators. I've placed a video of the action on the Meccano project page.
Getting there, slowly but surely!
