In 2005 I put up a photo of Rainman in St Kilda's Botanic Gardens, or as they are also known, Blessington Street Gardens. This is a better photo of Rainman by De@no at Flickr. Rainman is solar powered, so the brighter the sun shines, the more the water flows. It must have been a very bright and clear day when De@no took this photos as I have never seen Rainman going at this speed.
Sadly Rainman has gone, apparently for repair, but I think it has been quite a while, in fact years since it was operational. I hope City of Port Phillip, who is responsible for Rainman and the now quite disgusting pond, is part way through speedy renovations. I hope. Rainman's pedestal sits unused in the pond. The pond level is low, with murky water and thriving slime.
