I'm from South America. I am looking for a solution to build a shopping cart. The cart must be interactive, or will be 6 illustrations, each with a price and when you drag the virtual cart, a field must be showing the total sum of such products.

What tool would you recommend to design something? I was thinking about Flash, but perhaps there are better alternatives today(like HTML5). Or maybe some of you know any interactive car is sold to reach and use.

Thanks!
