Hello, I am designing a website and would like to add in a virtual kitchen where visitors can select a countertop and have it displayed in the kitchen. The kitchen itself would just be a generic kitchen and possibly have it so the cabinet colors would also change.

Is there software out there that you could recommend that would do this for a website ?

Thanks in Advance !

maybe you could use Flash

Flash will help you, but if you're looking for quick, easy and free or cheap that's something you're not going to find. It would have a limited application at best. That's a true DIY application.
