Original. I like it. I also like how you used the Apeture (sorry if I butchered the name for that) Science logo for the working in background and busy cursors.
Portal Crosshair Cursors
A set I've had sitting on my hard drive for months. There's already a better portal crosshair set on here. These are just something to throw out there. They all look the same, the roles are hard to distinguish, the pixelation is awful, and you can't see the dots.
