I've been out of the EE world for a couple of years now, but looking at the screenshots of KiCAD schematic capture tool, it looks remarcably simular to Eagle (same colors, graphics, etc). Are KiCAD and Eagle related in some way?

Nope, they're completely separate. Codebase, people, timeline.

Eagle predates KiCad by a wide margin, iirc. KiCad started in France, Eagle was German (iirc). I think modern Eagle is on Qt, KiCad uses wxWidgets for it's GUI library.
