Like the idea. One thing to consider: it's a little hard to discern the product/service. Take, for example, this one: http://cl.ly/image/0P0Y1q1r3p0N. Without mousing over the element, it's impossible to tell what the product/company/service is. (ICBW, but isn't that a Chrysler in the background?)
I don't have any dog in this fight...but Braintree isn't cloning Stripe. If anything, it is the other way around. To be fair, I think Stripe took Braintreee's concept and made it much simpler/cleaner. But to say that Braintree is cloning stripe is dishonest. Braintree was way ahead of Stripe in the tokenized payments arena.
