<lsl> // ~ RANDOM PROFILE PROJECTOR v5.4.5.20091126 by Debbie Trilling ~

// *** This script randomly selects an AV from a crowd & then displays their // profile picture as texture on a prim and/or a 'holographic' image projected above the prim***

// Free to use as you wish by under condition that the title and this introduction remain in place, // and that due credit continues to be given to Moriash Moreau, Coder Kas and // Debbie Trilling.

// 2009-11-24 VD - mod to use <meta> tag, to work around WEB-1383 // 2009-11-26 VD - add fallback to <img> tag in case the profile changes are reverted

// TOUCH to switch ON and OFF

// how often in seconds the sensor fires float RepeatTime = 35.00;

// sensor range in meters. Maximum 96m but in practice 10 to 30m because of particle draw distance float Range = 25.00;

// sets the number of consecutive times that the scanner is allowed to operate without having located an AV within range // eg: if RepeatTime = 60.0 seconds and TotalNoScansAllowed = 30, then the toy will operate for 1800 seconds (60x30, or 30 minutes) without locating // anyone before it automatically powers down.
