They are called star filters and commonly come in 4, 6, and 8 points. Fun to play with. For the 4 point make sure to get one that is a two piece and rotates to give the desired alignment of the points. otherwise the 4 rays of light can end up at odd angles. Not so noticeable with 6 & 8 points.
Okay. Good thought. Thanks.
