A
visual thing you say? (ironic that it tries very hard to look exactly like Photoshop)
Ok it only does gradients, but still, I'm sure it wouldn't be too hard to knock together a text-shadow (or box-shadow) example. In fact, I might just do that...
edit:
Plus, it's more than just "a few clicks in Photoshop" – you first need to create the image, specifying what size you want it, then enter the text, then do a few clicks, then need to upload it to the server in the right place, then change some text files to actually reference the image, then like Peter said, possibly make another version that looks good on a smaller screen.
Also, using CSS like this means you can make your fancy effects big as you like without affecting filesize, and including it in an existing CSS file means one less HTTP request, = faster site.
