Black Thunder is one of my all-time favourites and I've got a pretty extensive collection of his pics (it used to be a fairly comprehensive collection until a computer failure put paid to that.
IMHO, Black Thunder is the greatest porn star who never was. My understanding is that he made one solo jack-off vid a few years back but that was the limit of his video career. He has, of course, been the subject of numerous photoshoots and has a celebrity dildo modelled after him.
He seems to have faded from view over the past year or so, I hope that's just my perception and not because he's retired from the business.
cheers
