it looks good for linear stuff.
2 things though
first
the blur only effects the bounding box of the sprite
so if you look closely at the example cap, there's is a boxy edge to the blur when you move around
second even if it takes extra events (or a tiny behavior I'm willing to write for this)
it should blur based on actual movement
like if your sprite moved down right then down the blur should be curved
it just doesn't look right for curving motion
is that possible to give it a list of previous coordinates and have the blur go around a curve? (like I said I can make a plugin or behavior to go along with it to make it work automatically)
or would that be too many commands, or run too slowly?
