More experimental stufff

I added a 'miscellaneous experimental stuff' -section to the experimental stuff section. That stuff is not available for download so there's now two new things you can look at. One of them is really cool so it's worth checking out.

On the other news, Strafe is going to be released this summer. Maybe even sooner rather than later. Anyway, I also updated the one screenshot that there was for Strafe to show a more recent state of development.
