Here's a silly activity that has trueSpace interacting with the web.

Based on the script 'GetUrlHEAD' which is included in the scene. It uses xmlHTTP to fetch the header fields of a HTTP request.

'Get Futurama Quote' reads the HEAD information from Their headers are unique in that they add a random quote from the TV show 'Futurama' as an X- header. The script looks for any of three X- header values; X-Leela, X-Fry, or X-Bender, returning a filled string or null. The return strings are tested to provide a flag for invisibility. If the string is null, the linked figure is invisible.

I put together a very simple 3D visualization of the results. I could have made it into a game. The quote would be displayed, and you would have to choose which character said it. Alas, there are only a limited number of quotes, and I only have limited time.

This function can be used for a more serious purpose. I use a network monitor named 'Big Brother'. The all-over network status is carried in the X- headers, so I won't have the overhead of fetching (and parsing) the whole html page from the application's web server. I can just look for the specific X- header with my data.

*** Note about security ***

The function will fail unless the following steps are taken.

From the Control Panel

Open Internet Options

Security Tab - trusted zone - Custom Settings

Set "Access data sources across domains" = PROMPT

temporarily add '*' to your trusted sites.

You will be prompted each time you run the activity.

I'm not using the native xmlHTTP interface, but the following link is informative:

Very Cool early! It's good to see truespace scripting used in a unique way like this.

I was searching last year for a way to accomplish this.
I was looking at totally different ways, none of which panned-out.
This is very cool indeed!
I will be investigating this for sure :)

I agree, very cool early. I've been wanting to see more interactivity with websites. There is much potential in that IMO. Nice work. I too will be examining it. :)

Thanks for the kind words, all. I'm definitely looking for feedback, especially on the greater project: a network visualization, monitor, and administration tool.

I'll be posting some other bits and pieces soon. Send an email from trueSpace. Fetch a binary file from the internet and use it as a bitmap. A printer animated by a variation of Norm's 'Robot Arm' LiveScript.

Or, I could go buy Spore, and disappear for a while...

no no no... you don't need Spore.... :D

See, you need to make these groovy tools instead!

I've found that to have the 'GetURLHead' object work repeatedly, I had to clear my internet cache and set the browsing history to 'check for newer versions of stored pages: Every time I visit the webpage' (Control Panel - Internet Properties - General Tab.)

This will insure that new headers are fetched each time. is a privately held community resource website dedicated to Active Worlds.
