Roman Ormandy, Caligari's founder and ex-CEO, posted on the company's forums that Microsoft has decided to keep the website up and running for the next five months. They also just posted the last beta version of the software, 7.6.1.

The software, training materials and everything else on the site is available for free download. Once you get past the shock of the garish UI, the software really did have a lot of cool features.
