I don't really like my current logo. It's difficult to understand. People think the symbol looks like an "o" so, they sometimes read it as OizzyVideo instead of "IzzyVideo". Also, I don't think it's dynamic enough. I want something with more color, something that looks more modern, and is easier to put on websites -- and something I can use at the end of my videos for branding.
Also, I think the aperture/iris is a little cliche for video. I'd like something with more impact and style.
Logos I like:
Of course I like the Apple logo. But everyone does, and I'm not sure that could be done with a video logo.
I also like the playfulness of Skype, the colors of 99 Designs (in fact I like the look of the whole website).
I don't really like YouTube's logo much, although it clearly makes sense for them.
I'm looking forward to seeing your ideas!
