The website seems to work for me. Even jumpshack.com redirects to them. Aha.... "plabsinc.com" works. "www.plabsinc.com" fails. Despite the latter being the link on their facebook page.
Although even for the version that works, the intro page is blank except for a "Skip" link to the real page -- Maybe the first page had some deprecated Flash animation or something that is so, I dunno, 2005?
