Working animated dice download?

I'm trying to get some real old-school tabletop RPGers to play online. They stopped playing years ago when they all moved, so I'm fighting a lot of inertia in addition to tech-resistance. The closer I keep it to tabletop, the better chance I have of actually getting them to do it.

I'm exploring a few bulletin board and chat programs, plenty of options, but now I'm looking for dice. There are plenty of dice-equivalent random number generators, but it just isn't the same. What I need is a random number generator that actually has the animation of rolling dice -- *all* dice, not just d6.

The problem is, they won't want to download a full-on RPG online world. One of them owns a game store, I'm pretty sure he'd boycott on principle. A couple of the others are a bit technophobic. I need JUST the dice.

Does anyone know a download or website that would work? Thanks!
