No particles arnt 3D...they just always face the camera, it generaly is used for fire and such...the carrot was just because it was requested as an example !

Just out of interest, how complicated did you find it ...have you got a reasonable grasp of it yet ?

-EDIT-

Heres a zip with some more particles for you to play with I found them on free sites which was cool.

Have a try at these effects they are pretty cool ! Just pick the texture and set the values to what you see in the pics.
