As it already known CodeGear has publisher set of “Built with” and “Powered by” logos. Read more: BDN Feed (source), Nick’s and David I’s blogs.
Well done… almost… 
It took CodeGear/Borland a few years to come up with them, but they are finally available.
Just to mention, if you are looking for alternatives, there are still available from my web-site here.
I don’t understand why CodeGear needs to show their linkage to Borland when they tried so hard in the early days to show that they were independent from them. Anyway I prefer your logos over the official ones.
