I changed the “under construction” image to one of my old extended-exposure photos with altered brightness, contrast, and an overlayed elliptical-gradient alpha mask. Here it is with the original for comparison:

Not so simple: layering divs with different alphas and background images

I was thinking of just doing this for browser compatibility:

<!--[if IE]><meta http-equiv=”Refresh” content=”0; url=http://www.firefox.com/”><![endif]-->

Which uses IE-only “conditional comments” to redirect Internet Explorer users to the Firefox download site — kapow!

But I’ve decided not to be a jerk: IE 8 renders correctly, and I’m just going to pretend earlier versions don’t exist, like Google.
