searching for extension

[wshtek]

i need an extension which enhances/elaborates the product's options similar to the one here:

"zazzle.com/provo_utahlarge_letter_scenesprovo_ut_2_t_shirt-235434025116008238"

I've searched the marketplace, etc. and tried to identify whatever extension they may be using, to no avail. If anyone can point me in the right direction I would be in your debt!
