Yup. In my time of semi-downtime here, I'm playing with some LiveCD operating systems I have laying around.
1. Winternals ERD Commander 2005
It's meant to be a repair tool for Windows (the only OS that would have an entire OS written just to fix the former..) so it has no play-around toys, but it did have firefox (which performed poorly, find kept jumping up while I posted) which was a plus, except it's problem.
2. Ubuntu Hoary Hedgehog Live CD
The most software-packed, I think. I used it for a few hours last night to browse the forums, but it had a horrible resolution (600x480) and there was nothing I could do to fix that. But it did include both xchat, gaim, and firefox, so it was pretty decent.
3. Ubuntu Breezy Badger Live CD
One of it's packages failed a MD5sum check at boot so it claimed to be corrupt. Oh well.
4. Damn Small Linux
This one wins by far. It has a nice Window manager with some cool docklets (the bottom one is still beyond me what it does..). It also included XMMS and supported my DVD drive (I forgot automounting of CDs was an Ubuntu-specific feature, so it took me a few minutes to figure it out), so I was able to play some music without my harddrive working. It's got a decent resolution (I've seen bigger (smaller?) but it's a hell of a lot better than Ubuntu).
5. Puppy Linux
Nice, easy-to-use GUI (that Windows 95 impersonator WM). You're able to actually exit the Window manager and return to the command prompt, unlike DSL, and return by use of startx. It's installation wizard did quite a good job of explaining each step, but it wouldn't format the disk for you. Two major flaws: It didn't detect my network card automatically, nor offer any obvious way to do that, and it didn't have a way to open a command line in X.
