All work and no play
The stalactite and reflecting pool, with miners working. The detail in this photo shows the workings of the conveyer belt. The ore was glued onto an endless loop of fabric, but with the small retaining wall in front of it, it was a convincing portrayal. The water for the reflecting pool was on a recirculating pump separate from the preceding waterfall. Click on the miner in the background for a close-up view.
