Yeah, but I assume that's a version of Worldcraft, since they bought Worldcraft for HL1 from Ben Morris and brought him down to program it to suit their needs.

AFAIK it was the tool they used for HL2 and Portal as well, though it might have had a different name.

Portal has it's own puzzle maker that comes with the game.

I feel like I could make good use of a Portal gun on this tour.

If you don't know who Matthew Silver is:

"My role as a clown, trickster and village idiot is to parody excessive seriousness by playing with taboos, rules, and social norms. My inspiration comes from my heart. I perform for smiles and laughter, loosening people’s armor, and opening up a portal for imagination, creativity and love.

Some people see me as a raving lunatic, pompous “artistic” hipster, or attention-starved 9 year-old, but people don’t consciously understand the role of a clown in society. Read between the lines and you will start to see things from a different perspective. By breaking down boundaries, I provide you, the viewer, with permission to open your mind and realize it’s okay to act silly from time to time. We may trick ourselves into believing we know everything, constantly striving for perfection in a society that requires a civilized, job-holding, serious individual. We cannot be perfect. If we allow ourselves the chance to be flawed perhaps we can let the obstacles humble us, rather than make us rigid. In the end we can let our guards down to attain our most basic need of giving and receiving love."

I don't remember Portal's turrets stopping when you stop moving.

Was expecting less paint-ball and more Portal's turret.

haha, that things just a tad bit more aggressive. Saddly it looks like someone made a automated gun aiming rig and decided to dress it up by plopping an egg shaped styrofoam mock up in the center of it rather then actually build the guns into the egg shaped object like you are supposed to. They didn't even bother with building the same ai as the robots into the gun firing routine (complete with sound effects beeps). The whole portal thing was a complete afterthought.

Portal voice actress?

I actually knew a few of the people involved. DigiPen (where the students who designed Portal went) was just up the road (and my second choice for a CGI school) from where I got my education in computer animation. I used to hang out with Ben Morris who built level design tools for Doom and Quake back in the day and went on to build the level design tool for Valve that they used on Halflife and Portal.

I also worked on Navy Seals, the project Gooseman did before Counter Strike.

Sometimes I wish I could go back in time and keep collaborating with some of those folks instead of finding a different path (animating for TV shows).

And then she went to say hello to magic portal, the manhole cover?

HBO? When did it move to HBO?

On August 13, 2015, as part of a five-year programming and development deal, Sesame Workshop announced that first-run episodes of Sesame Street would move to premium television service HBO beginning with season 46, which premiered on January 16, 2016. HBO will hold first-run rights to all newer episodes of the series, after which they will air on PBS member stations following a nine-month exclusivity window, with no charge to the stations for airing the content. The agreement also gives HBO exclusive rights to stream past and future Sesame Street episodes on HBO Go and HBO Now – assuming those rights from Amazon Video and Netflix; on August 14, Sesame Workshop announced that it would phase out its in-house subscription streaming service, Sesame Go, as a standalone service; the service will remain in operation, likely with its offerings reduced to a slate content available for free or serving as a portal for Sesame Street's website.

The deal came in the wake of cutbacks that had affected the series in recent years, the changing viewer habits of American children in the previous ten years, and Sesame Workshop's dependence upon revenue from DVD sales.
