With Halloween only a couple weeks away, it's time to get your Mac into the holiday spirit ... with a screen saver! The free Jack-o-Lantern screen saver from Killer Robots does just that -- without the mess of carving a pumpkin. It has over 25 pre-made designs, but you can also create your own pumpkin designs in Photoshop using the carving template provided by the developer.

The screen saver features a very realistic pumpkin that rotates against a black background. You can control many settings including: seconds between pumpkin design changes, camera rotation, quality, and screen glow. In addition, you can select which designs you want shown. Check out our gallery of screenshots to get a feel for the quality of this awesome screen saver. You can download the screen saver from the developer's website.

If you want even more customization, check out the Icon Factory's Halloween section for free icons (compatible with Candybar from Panic). Do you have another favorite holiday screen saver or icon set you like to use? Let us know in the comments!
