Not a terribly good website but it works and I can read some more about the company I didn't already know. Since it's a bloody Flash site I can't link to individual pages I'd want you to visit, but when you go there be sure to find the "The SEMCO Management Model" which describes in simple and quick terms what this is all about.
There's also an interesting Timeline animation showing what they were up to in different years. Since I read the "Seven-day Weekend" a lot has changed in terms of their business offering. Nothing of what they do seems mainstream or at least they do well in rephrasing themselfs so that it doesn't sound mainstreamed.
PS. If you want to know why I'm blathering about this corporate website, read my review of The Seven-day Weekend
