Here's my first attept with a light trail.  Farris wheel at the South Carolina State Fair.  

This isn't exactly a cityscape but I was super impressed with how Cortex Cam worked for this night shot of the Starship 3000 ride.  I couldn't believe you could get that clear an image with low noise handheld.  What a great tool!

I'll post a cityscape if I can grab on over the next week or two.

Just tried the sway at the beach.  I showed it to my son and he said "Mom!  You broke the lighthouse!"
