I’ll check it out when I have time (after tomorrow’s physics exam).
I dind’t find this info anywhere - where are these guys from?
Can’t find that information either, I searched for the company/studio/team/whatever (frictional games) site but I don’t think they have one yet…
Edit: Oops, just noticed their e-mail address. This is where they are from: mainweb.hgo.se/adm/eng.nsf/
My computers specs are too low to run it. 
Shame, because it looked pretty cool, too.
Thread revival because the demo of Penumbra: Overture, the retail sequel to the freeware game/tech demo discussed here, has finally been released. The first of three planned episodes will be launched at the end of this month. Click here for more.
I have not tried it yet but from the screenshots and especially the videos found in the media page I can say that the concept seems as appealing as before but even better executed. Enjoy.
