Fun with overloaded lights

Just had to share this because I stumbled on it by accident.

Make a small prim. Set it as a light.

Use the Ctrl-Z method to duplicate it in the same place 7 times.

Link the 8 copies as a single object, and copy it down a corridor.

Result: Because the SL client only renders the 8 closest lights to a user (on a per-user basis), every user who walks down the corridor individually sees the lights following them down as each block of 8 becomes "nearest".

It's probably something everyone's known for ages but darn I've found it now.

Alternatively you could do blocks of 3 or 4 to make a series of lights that follow the user.

. = off
# = on

Uses fewer prims, has the same effect, and is just all around nifty.
