Here are some of my concepts. I've gone for something that's fairly clean and simple, yet striking. Creating an icon that works well within the logo or as a stand alone element, one that can be used for things like favicons or watermarks.
The logos are 100% vector so will scale well to any size, and works well in full colour, B&W and on coloured backgrounds if needed,
It would be my pleasure to work up any variations so please do say. I look forward to your comments or thoughts.
7 is my favorite from your bunch. Logo is cool, but I'd like it to jump out a bit more. Rotate it a bit so it's not quite vertical? Maybe a soft bevel or sphere shine to add a little depth? Colors are great!
