I had this awesome toy when I was little. It was a flexible ring of about 8 pyramid-shaped blocks, colored orange and purple on alternating sides, which could be folded together to make all kinds of interesting shapes (cubes, stars, octogons, etc). Sadly, my dog chewed it up, and I can't remember what it was called. It was a Japanese name, I think, and I'm pretty sure it started with 'y'.

I'd really like to have another one. Anyone know what I'm talking about? :(
