Where’s the “most viewed today” plugin?

I’ve been trying to find the plugin that displays your most viewed posts of the day… do you know where it is?
I’ve searched through the codex here and of course on the major search engines, but I can only find people who are using the plugin, and not the original site.

And to clarify, I’m not looking for Lester Chan’s most viewed plugin – that one lists most view posts of all time.
