Slate is a single day hack project that was intended to be a kickstarter, however the developer ran out of time so now it’s a partially-implemented IRC client. He had pretty lofty goals but unfortunately there’s not enough time to go around, there are still many features missing, and it’s not quite in a usable state, but with some community interest and love maybe it will get there some day.
It’s a clean, minimalistic IRC client, completely extensible through plugins. Ideally most of the core is written using such plugins. The entire thing should be themable, and the default theme should be programmer-friendly, and you can see chat logs.
