Long Lost Brother Of Microsoft BackOffice Logo?

The Mozilla Weave project released version 0.3 recently and their logo looked really familiar. Perhaps it was the long lost brother of the Microsoft BackOffice logo?

Maybe it’s just because I worked in an IT department many years ago where that BackOffice logo seemed to be everywhere, but I can’t look at that Weave logo without thinking of BackOffice. It’s like a shiny monochrome version of Microsoft’s rainbow.

What do you think, definite relation, or am I just scarred from my time with Microsoft BackOffice all those years ago?
