It's too bright!

Today we had a lecture with David Downes who specialises in interactives. While I was sitting in lecture Rob had his laptop open and Kane showed us some cool lighting effects such as a "sky light". Now, this light is absolutly amazing. Especially if you have to shadows turned on. There is one problem with it however, which is that it takes a lifetime to render just one frame! I think I will use this in my final piece but il have to leave at least a day or two to fully render everything. Here is what it looks like, click on the pic itself to enlarge:
