This is another trick that could be done by using a long shutter speed. If you have an ND filter at hand and a stable tripod and cable / remote release it would be helpful, but could manage without any of these. Only real requirement is a digital camera that allows manual controls.
The subject remains still during the length of the 2 second exposure but her eyes were constantly moving from side to side. I asked her to give a slight pause at the extreme ends to get this specific effect. Else you will get even blur without the pupil registering on both sides.
