The best of ImposionWorld.com is without a doubt the video gallery. There is also a small photo gallery but the pictures are small and not so amazing:
"(...) Here you'll see implosion photographs divided out by category. Yes. Categories include hotels, silos, hospitals, public housing, and sports venues, of course (...) If you'd rather see videos, check out the Implosion Live! version of the site. Here you'll find archived Webcasts for several implosions over the last few years (...) Other offerings include implosion world records, "blasts from the past" (brief articles on famous demolitions) and information on implosion/demolition media and exhibitions. Amazing."
