Hidden Mickey Design

[CDX4]

I'm on the hunt for something I saw a couple of years ago and I thought one of you might remember. Someone had posted a picture of glass bubble magnets they created using different hidden Mickey designs. These were refrig. type magnets that you can see the design through them. I'm looking for the designs that were used. They were the most subtle non-Disney looking designs that had hidden Mickey's in them. They were in a deep green, sapphire blue, and maroon. Anyone know where I can find these?
