This is a small Sears Tower LEGO model (the only LEGO I have) placed in front of a computer monitor displaying a simple vertical gradient. Reflected in the LEGOs from the right is a printout of a grid of small squares taped onto an IKEA lamp; reflected from the left is the same grid, but color-inverted and displayed on the monitor. Aperture was f/22 to get a sharp image throughout, especially the reflected windows since they have a different focus point than the LEGOs.
