Pebble Rubik's Cube
I could do the rubik's cube as a kid. A minute and a half was my record. We used to put vaseline on the inside of the cube so that it would spin more quickly to help in solving it rapidly. I don't think I could do it at all now let alone do it quickly.
A few years ago I made a pebble sculpture at Loch Lomond in Scotland. It's one of my favourites as it was the first time I really studied the pebbles on the beach and discovered the multitude of colours present. I was rooting around in the garage the other day and I found a bag with some stones in. I had no recollection of keeping them but it seemed I had brought the pebbles with which I made that sculpture back home with me. I am not sure why I did but it was interesting to see them again, to admire their different colours, after looking at that photo many times.
This cube has three of the colours - white quartz, pink feldspar? (guessing on that one) and purple slate.
