I found this little design on flickr, its laser cut from reclaimed aluminium. It’s the work of Don Solo who in his own words is “just a geek being a geek for other geeks.”Apparently the design is based on the Weighted Companion Cube in Valve’s game Portal. He made a few of these key rings for friends, then the key ring began to get a lot of views on flickr (65 000) and people started asking if they can get one of them. So generously he began to give them away to people who emailed him. However that came to an end because someone sold one on ebay trying to profit from his generosity. Since then he decided to try selling them on ebay himself and was surprised to find that people were willing to pay $53 for one of these little laser cut pieces.
It’s been really successful for something that was never intended to be sold. Quite inspirational really, it’s just a key ring but from reading the comments on his flickr site people really love them. It’s a great advertisement for laser cutting; anyone can design something and then get it produced cheaply to a professional standard and then hopefully be really successful like this key ring.
