This was the best shot of my first attempt.
Using a Nikon D3100, my 18-55 VR lens. My F-stop was at 3.5 - the lowest this lens will go.
My focal point was the computer charger.
I used the lines in teh floor leading to the charger, the foot of the entertainment center leading down to the charger, and the bottom shelf of the entertainmetn center leading up to the charger. Additionally, the rail fo teh swing leads over to the charger also, but not quite as well.
