Uploaded a demonstration video of me using the Portal Wrench. I could've done a little more in the video, like shooting weapons through them, but I wanted to keep it fairly short, to save on both disk space and upload time with my measly 30 KB/sec upload speed (or lack thereof).
Also uploaded it to YouTube... like 10 hours ago. It's still processing. So I decided to upload it to Google a few minutes ago. :P
