It allows you to draw on the 3d environment itself in wow, and then save/send it to other players.

Need to know where each mak has to stand on a boss fight? just put a symbol under them when you're setting up and people can run to that symbol, never expires will always be in the same place when you come back the next time, excelent for when you're bored and want to draw to pass the time, also a new way of abusing neltar which is always good. Oh and it works with boss mods to do stuff automatically for you

Er nú ekki búinn að prófa þetta mikið, en t.d. í ICC á rotface sýnir þetta hvar slime explosion lendir, setur timer á duration á slime debuff draslinu þarna fyrir ofan hausinn á spilarananum, á Festergut sýnir þetta radius á spore dæminu, sýnir explosion radius á malleable goo á putri etc.
