Looks awesome. The Kinect could be a fun way to explore your visualizations -- seen here hooked up to Google Earth: https://github.com/jawj/pigeonsim Also, I'm sure http://www.bartlett.ucl.ac.uk/casa would love to hear from you.

Thanks George. I replied on Twitter but worth saying here also… I saw Pigeon Sim via Andy @ CASA the other day, it looks like awesome fun! We'd also like to play with Leap Motion and create something similar to the Google Liquid Galaxy stuff. Quite keen to work with CASA, I'm sure there is a tonne that we can help each other with. I told Andy about the project a while back but that was before we had anything visual.…

Leap Motion has JS plugin so it would be super easy to integrate with it.

Any chance you could put that up / a version of it up on jsFiddle or something so I can edit it online and see how I can help? There's a few techniques that I could play with. 1000 objects should be silky smooth…

Absolutely! Give me a few hours and I'll have it up. Thanks for the offer. Also it ended up being 6000 objects because a box is 6 planes. I wanted to reduce that to only visible planes but because boxes could be partially translucent depending on some property and be selectable when clicked, it would look weird if inside sides were missing.

Cool, I'll keep an eye open for the link. Even 6,000 objects would be fine, especially if they're cuboids. There are demos with 120,000 cubes running at 40fps+, or even 500,000 cubes if you want to use fancy buffer geometry techniques.

Crossing my fingers real hard for somebody to pick this up eventually to make a no-nonsense FOSS SimCity clone out of this. Please, please, please.

That would certainly be kinda cool. My recent background is in HTML5 games (I used to work at Mozilla) and I'd love take what we've done so far with ViziCities and see how a game would look.

Wow, very interesting, this tickles my fancy... Imagine something like this but with an airfield, you could model the airfield and every airplane landing and getting up in real-time.

Thanks! Real-time air traffic (inc. landing and taking off) is something that we're looking into.

Let's hope so! I've applied for a dev kit so hoping I get accepted.

Really amazing to get this after only one month, when you know how difficult is building 3D stuff !

Thanks! It's definitely easier when you're standing on the backs of free software (like PostGIS and Three.js) but the 3D aspect has certainly been tricky.
