It's called Low Voltage, and focuses on an electrically unstable testchamber. There'll be a main room with a few moving platforms, and three or four additional rooms where each one will activate another platform, enabling you to progress further. There will be some BTS action. Also I plan on adding one or two small testchambers intended to teach a fling method I've been working on.
I'm completely new to Hammer as of two weeks ago, but I have a high standard of quality and I believe I picked up Hammer fairly quickly.
That said, this first room took me about 10-14 hours to complete, however much of this time was spent staring at the room wondering what I wanted to do with it, and exploring special-case entities that were used, like sparks and explosions.

(clicks) Image Notes: Turret toggles by button. Indicator strips from turret to switch (not pictured), and each button to checkmarks will be added. Lighting and textures will be improved.
Feel free to comment.
