So, last time I was informed it's called a yoshimoto cube, though a proper yoshimoto cube you can take apart to get two stars, and this is just the cube
But anyhow, second one, a teammate at work got jealous when he saw the cube I was making for Helena ("but she's not even on your team... *intense stare*") so I made him one as well, for his son Elias.
Video just so you see how it works: http://www.youtube.com/watch?v=JnnOdu3DW7M
I embroidered spades on it because I couldn't find any spade-fabric, and Elias is obsessed with his spades - he brings them everywhere he goes.
I'm especially fond of the yellow-green one, I think it stuck pretty close to the original.
The pattern was freehanded straight onto the fabric, like so
Here's the link to the previous cube, for anyone who's interested
It's got a link to a longer video too http://www.craftster.org/forum/index.php?topic=296493
(there's a link to a tutorial there too, but that tutorial is not as color-strict as mine)
Hope you like it! Elias seemed to anyway
