Every week, Rob Zacny crosses the chasm of Early Access to find a treat on the other side. Sometimes the path across is perilous, sometimes it is as sturdy as a horizontal oak.
As something rolls across a painstakingly-constructed series of spans and supports in Dry Cactus' Poly Bridge [official site], you can see the structural elements changing color as load is added or subtracted and they draw closer to their failure point. A car followed by a heavy bus turns a set of struts and arches from a cheerful green to a neutral yellow to a wary orange to a bloody red, and it's right at that moment the excitement of civil engineering comes to life.
If that piece can just hold, and the car rolls onto the other half of the span with its added supports and pillars, then you've done your job and built a useful bridge. Alternately, the piece will wobble, collapse, and dump your passengers and a good part of your bridge into a canyon or a river.
