I found a funny 3D game: "Sumotori Dreams"
You can get it from here(http://www.download.com/Sumotori-Dreams/3000-7416_4-10669340.html?cdlPid=10669339).
I came up with a new play manner.
You can throw blocks to any place you want on menu of Sumotori Dreams.
And so you try to build up block like below.
Can you build up more than 4 blocks? :-)
