3x3 mod

I got a 3x3 rubiks brand cube but i have no idea what to do with it. I would like to mod it into a Siamese but i dont have another cube so i wanna know if there are any other mods out there that i can do with one cube. Thanks!

Im selling a custom 3x3x mod. Its made of a 3x3 color cake found on lightake.com. its a great fun puzzle to solve and it has parity. if interested email me at [email protected]. im willing to sell it at $10 but we can negotiate a fair price plus shipping.
