Together with my team I'm working on a small indie game "Runes" for the Leap Motion technology. While it's not a Arx Fatalis remake project, it's still one of our inspiration sources. I think you guys will like this

It's an arena combat game where druids of different clans fight for political power. Battles take place in temple-arenas and are fought with magical runes. The player uses the Leap Motion to draw these runes on the screen and can then cast them towards the enemy player/NPC. It's a game that's all about skills and wits. The player has to learn the runes, their power and weaknesses. To win, you need the right strategy and perfect timing; it's like playing a cool, expanded, fast-paced version of rock-paper-scissors. Leap Motion is, for us, the perfect technology to make this game as immersive as possible, where the player really feels like he is actually casting magic, instead of just pressing a button to do so.
Two dev updates have been released:

We would love to get some feedback from the Arx Fatalis community.
