Peter Parker again? Lets see Miles Morales on the big screen! (Yeah, it was Peter in the 616-CivilWar, but given how the MCU adapts comics-canon? You can't tell me Miles wouldn't be a great fit, especially given the greater risk a young black super-hero in NYC runs by unmasking.)

Vitally important as it is to protect children from sexual predators (which of course includes the market for child pornography), I'm concerned that including general child abuse in this will both silence child abuse survivors and make it more difficult for abused children to ask for help or advise anonymously online. I don't think differences in English usage across the world should override this.

There's a lot of variations on "realistic human 3D models are difficult and expensive, therefor CGI software is unlikely to replace photography anytime soon" in the posts above. Wanted to point out: DAZStudio4Pro is currently free (along with its companion programs Bryce and Hexagon) and comes with an androgynous free human figure (called Genesis) that can be easily worked into a wide variety of realistic men, women, children, aliens, and demons:

The site (and several others) sell presets to easily make Genesis into various realistic characters, also lots of 3D clothes, props, and scenery -- but, like Blender, DAZStudio4Pro is free (unlike Blender it's not open-source, has been paid software in the past, and almost certainly will be again).

Plenty of examples on the site's forums of extremely photo-realistic 3D human renders, too: http://forum.daz3d.com/ , try starting with http://forum.daz3d.com/viewtopic.php?t=189377 and http://forum.daz3d.com/viewtopic.php?t=165191

When you say "from the ground up", do you mean literally? If so, you should start with a building that's not only fireproof but disaster-resistant, is energy efficient, low-maintenance and yet attractive, and costs little more than a standard structure while being faster to build. You want something like the building shown here: http://www.monolithic.com/gallery/commercial/office/index.html

Different design (with floorplan and site layout) here: http://www.monolithic.com/gallery/commercial/stardome/index.html

Plenty more commercial structures here: http://www.monolithic.com/gallery/commercial/index.html

I'm in no way affiliated with Monolithic, I've just seen their work and know they can give you what you need. Oh, and they're better at building structures than they are at building websites. Really.
