These are actually pretty good.

Haha, it may look neat at full resolution, but in game these look like utter stuff. Have you even tried putting these in game?
Crud your right... I made a few that may actually work though let me get them
I think that it might work if you re-sized them down to the dimensions of the original crosshair, then made them slightly transparent.
The shapes are cool, but they need to be the right size.
