Amazing images of vacuum tubes

There's a site called RadiologyArt with beautiful CT scans of common objects, including KT88 and EL/34 vacuum tubes. Still images of those two are on the right side just below the middle of the page. Don't miss the movie of the the EL34 tube near the bottom of the page.
Cool link, thanks. They should have some Pink Floyd music playing in the background of the EL34 tube movie though, IMHO.

Appreciate the knowledge.
