I'm an independent, third-party developer for VALVe's Source engine, with specific emphasis on developing for Portal with a pinch of Half-Life 2. My current undertaking is a full-scale mod entitled Portal: Stay Inside.
This is a teaser image for my upcoming Portal map, Longevity. Details and more media to follow. My promise: no filters have been applied to this screenshot or any others I make unless explicitly noted.
This looks awesome!
