Hi, all! I think this contest was a success, it forced you to think and invent a way to overcome a never before seen obstacle in AR. You'll be surprised to find the diversity of the "tram cars", look at Votart's "Light stupid" and rob's ultralight-dark trolleys for example.
So on to the results...
mx781 with $3553 (the same design as markmadras, a little difference in the catcher and holder area, you have to wait 600s)
mi2 with $3953 (when I got ioncorpse's solution, wow.. I thought he'd win for sure, well, that was a mistake )
I don't know what secret thing ioncorpse talked about, maybe it's the length that makes the bar REALLY heavy and so causes some strange anomalies in the anchor points or to the bar itself.
Thanks for your different and innovative designs, see ya in the next contest
