Few souls on HN will remember as far back as the (ahead of its time) Amiga / NewTek VideoToaster, but Showbox reminds me of how I felt when I first saw the 'Toaster.<p>One view of Showbox is that it's basically a browser-based version of something that 20 years ago was a industry-changing hybrid hardware/software workstation, and I think that says a lot for how far we've come.
