Thanks for thinking of me, Maizey. While not really into random push photo galleries, I much preferred Astronaut's approach. FlickrTime just couldn't deliver on its promise to limit searches... maybe because people don't fully grasp the "tags" concept.
FWIW, I used Waterfalls and Moss as search tags. While FlickrTime sent me some photos of waterfalls, it also kicked out a lightbulb, 5 identical headshots of someone sucking a lollipop, the Woolworth Bldg in NYC, a stunning nude, and this, um, eyeopener.
The next time the "random" mood strikes you, may I suggest an idle time questing "game" I started for myself years ago. Pick a word, any word, noun, verb, adjective - fractal, dreamcatcher, melancholy, escher, purple, legs, cloud, angry, cube, prism, tattoo, butterfly, waterfall, vortex, ocean... whatever, and then Google Image it. Stumbling down unexpected tangents and wandering through sites I might never have had reason to visit simply because an image looks intriguing (or totally out of context to the word searched) provides a neverending source of entertainment and education.
