I have project wonderful on my site sandboxdrama.com but I've been planning (for few months now) to place some buttons there or add a links to my links page, which cries for work to be done right now I was thinking about buttons like 50x50 px. Or perhaps 117x30px (it's the PW button size) or something eventually.
There's basically always some free spots on my site at the bottom of the page. Project wonderful buttons, feel free to use them if you feel like it ^^
