Overview

Chromutate is an interactive building/installation I'm working on - an excuse to play around with both Reflexive Architecture and the new HTTP-in LSL features. Feel free to visit it (from the web or in-world): change the colors of the building, rez stuff, send messages.... Take a copy of the scripted objects if you're inclined so, and please warn me if something doesn't work!

Ideas that could get into Chromutate

Tech

I use Gridurl to maintain persistent URLs for my LSL scripts. See the code below.
Disclaimer: I'm not a real programmer and your comments and suggestions are welcome.

For the HTML, look the web page source. Here are the LSL scripts.
The main script below receives data from the web page, where you can choose colors and something else through a form. The script then parses those data and does some things with them - it rezzes an object (or not) and it relays the parsed data via chat channels to other objects.

first script - it manages HTTP calls and talks to Gridurl
