Our current logo was something I created and, while I like it, I find the "atomic symbol" is a pretty common element and therefore does not really uniquely identify Atomic Powered as a brand, even when integrated into the "Atomic Powered" logo. However, I do like a logo with a "scientific" or technical feel.
I also like having something iconic from the logo that can be used as a standalone logo to represent the brand. I've currently been using the "atomic symbol" for this but, as I said, that is not as unique as I would like.
I also like the association of the "Atomic Age" which to me still provides a sense of the future. I would very much like to logo to communicate the future and the cutting edge.
Finally, I would prefer not to redesign the colors of my website (http://www.atomicpowered.net) so the logo should work with the dark backgrounds of the site.
