Fun little script. Drop it in a prim to see how it works. Demonstrates how to work with the map api.

<lsl>string URL = "http://www.subnova.com/secondlife/api/map.php?sim=";

key httpRequestId;

float mapSize = 3.0;

mapParticle(key mapTexture) { 

   llParticleSystem([PSYS_PART_FLAGS, 0,
                     PSYS_SRC_PATTERN, 4,
                     PSYS_PART_START_ALPHA, 0.5,

   state_entry()
   {
       httpRequestId = llHTTPRequest(URL + llEscapeURL(llGetRegionName()), [], "");
   }
   http_response(key request_id, integer status, list metadata, string body)
   {
       if((request_id == httpRequestId) && (status == 200))
           mapParticle(body);
