Ok, early 2000s aesthetic sans a flash intro. But we're talkin' internet years here so you're still rockin Air Force 1s, but their as popular as ever. And like I said earlier - it doesn't matter.

I know its your baby, but if you managed this with wordpress or another CMS, it would be really easy and you could be much more flexible to add new things.

I could recreate your whole site in about an hour if you'd like.
