A screenshot for the Half-Life 3 video game?
Unfortulately, the era where I am hooked into top-secret game previews is long past. Actually, if I knew anything about upcoming games, I wouldn't be bragging about it on JSVB.
The reality is that this is a photo I took of some water feeder pipes for the Stave Lake Powerhouse. Operational beginning around the 1920's, it's a popular site for Vancouver-area filming. It's a great place to see gigantic iron and steel machines from the age of Art Deco.
