I created this small mod for the TWHL.co.za Competition 28 - Map a Dream, which ended on 30th August, 2010. The original concept was to create a really dreamy map of any theme, which would be judged by not only geometry ambience and game play but also the dreaminess of it. This map achieved 3rd place.

Note: It comes in mod format for Half-life1, and Is originally intended for steam Half-Life only.

Edit: Sorry for the bad image, I will get a high quality one later on.
