User:Opensource Obscure/Chromutate
Chromutate is only a cool portmanteau for a simple idea: fill in a web form and make things happen in Second Life.
It's also a building/installation I'm working on (but I'm not pretending I'm doing art here), and an excuse to play around with the new HTTP-in LSL features.
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.
Feel free to visit, change the colors and warn me if it doesn't work! SLURL
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
