Yikes, those close-ups are a bit unsettling...nicely done. I was bit by some unknown creature (likely a spider) about 5 years ago which affected how I now react to other bites - they first puff up then scab over and hang around for a week or longer. I showed one such bite to my dermotologist, who wisely pronounced that I now have 'Persistent Bug Bite Syndrome' -- what a hoot!
