Had this idea for a couple days. Not meant as a replacement idea. I just like edgy.
Great addition of the octagon, I felt like it was missing! Interesting that you added the clean vs dark backgrounds. I was under an impression of a completely new "modern" (jokingly, edgy) style could be built around the new concept. I'd have to get back home before posting some ideas possibly concepts. EDIT: Or an alternative styling overlay like Zen.
If it's a new "style" it should be called "Falcon."
I've turned this into an SVG here. Fully compatible with the existing logo and CSS, as demonstrated by dropping it in through the developer inspector pane. Note: Not suggesting we change anything, but it was fun experimenting with SVGs :) Edit: Changed it so the sizing so it should be a bit better, kept the old definitions in there so people can experiment -- just rename trapezium the one you want to test out!
It looks like the loading icon of a video game, I like it.
