My latest wallpaper took a bit of time, since i had to vector 4 cars and do the entire background from near scratch, with some help from [link]
for the effects used.
It's based on the 200mph club, taking the base models of the top few cars that cross 240 mph, a hypercar club if you will. I didn't include the Super Sport version of the Veyron, nor the CCXR from Koenigsegg, i wanted to use the base cars on this wallpaper and i think it turned out quite nice.
Done in PS CS5, using text tool, pen tool for the cars and lines, some faded images for the worn effect and a lens correction filter for the vignette.
Download for 2560x1600 wallpaper (quite large this time because of all the effects) Enjoy
