Did you know?
When I joined OSG, I was utterly fascinated by NPCs, it was such an alien concept for someone fresh from SL.
But of course when I rezzed NPC #30 I realise I needed something to wipe them out easily and I didn't have any utility for that, so I made a quick script.
Later I decided others may want it too so I made a mesh for it... a bomb.
This unassuming object is an NPC remover, you can have it handy somewhere and it'll wipe all the NPCs from a sim with one click. Feeling evil yet?
