Light painting in the train tunnel last weekend.
The tool used for the orb was a frosted acrylic tube attached to the RGB control unit of the @buyfiberflies Pixel Whip (scroll for pix).
After creating the orb, I then walked over behind the camera and illuminated the tunnel with the same RGB torch.
Single exposure: 10mm, f/4.5 ISO-800, 100secs
