roadmap art

I've been working with drivers@mozilla.org to put together a new milestone schedule and that means an update to the roadmap graphic that I've been maintaining for a few years. Shuffling through the directory of old images I was reminded how cool Hixie's original roadmap artwork was.

Here's the oldest one we still have on file. I think it's Hixie's art with only minor mods by me:

Here's the first of the "new style" images I did:

What do you all think? Should I keep going in this direction? Move to something less geometric? Get out the dry erase markers, paint something on the whiteboard, photograph it, and publish that?

I'm intimately involved with the roadmap so I don't usually need to check the picgure for schedule information. It's for all of you so I'm certainly open to criticism and suggestions about how to make it more useful.
