Not sure what the problem is with linking youtube videos on this forum but I just noticed that the video I linked to in my second post has now been replaced by one of the videos from a later post. I also had a similar problem with the videos in that later post. What's up with that?
I'll try posting the correct video again but my guess is that sooner or later they will get switched again.
Edit: Now it's getting really weird. As soon as I made this post the second post corrected itself. What's next? Twilight Zone?
