I didn't even know there was a bounty. Awesome.
By the way, I am working hard on updating the explorer code, and the HiroCoin explorer will receive all updates going forward.
If you wish to run this on your own machine, please contact me or wait until the next version, the source code will be available on github shortly after the update to 0.42.
Thanks. Please give me a link when it is done as I may well put it on the official site. I'm guessing that comes complete with styling?
