Hey up, as I recently had to halt the progress on building Daemonen, I got a bit bored and set myself a challenge ... I layed down a reasonably small rectangle on the floor with supports and tried to fit an entire B&M floorless in there, I spent about 5 hours on it and eventually ended up with what I think would be a pretty damn instense ride in real life.
Here are pictures:

I don't want any testers, I just thought I'd bring this to people attention, so they could look out for it in the track exchange soon. If anyone could lend a few ideas as to what the colour scheme should be though, please feel free.
