What better way to celebrate Halloween then with an iPhone app or 10. Below are 10 of our favorites. All are ghoulishly good fun and will get you in the Halloween spirit. Plus, these will give you something to do while you are hiding in your house, pretending you aren’t home and eating all the candy yourself. You disgust me. But if you share some of that chocolate, I won’t tell.

The scarecrows of yesterday were designed to be scary. As the name implies, they were there to guard crops and keep crows away. It could do with an update however. These days crows and other animals are smarter.

This conceptual scarecrow is armed with an infrared sensor eye that can detect animals within a 16,000 square meter range. When an animal is near, it will go into in an Ultrasonic Wave Generation mode. The device would be equipped with solar panel wings, making them completely self-sufficient. Any varmint that gets too close will suffer a small jolt to scare them away.

LED-embedded undergarments are bizarre. Maybe even creepy. I mean, look at the pic. It looks like you have an evil other-worldly creature living in your nether regions. Do you really want that thing staring at you? But hey, maybe you like that sort of thing in the bedroom. Who am I to judge?

I guess LED undies are only limited by your perverse imagination. At Enlighted, you can get LED g-strings, panties, even hot pants. If it’s not freakish enough for you, they will make a custom piece for you, with lights and patterns of your choice. Perfect for acting out Sci-Fi fantasies. Just don’t ever talk about it outside of the bedroom. Please.

The Roswell the Alien Wall Plaque has a few different uses. For one, it makes it look like you caught one and imprisoned it in your wall. Which is good because if a real alien shows up one night to abduct you for study, he’ll see this on your wall and hightail it out of there. Plus, he’ll tell his friends and thus you will be safe.

It’s also the sort of thing that comes in handy for scaring away unwanted house guests who like to spend the night. Just put this up in your guest room and no one will want to sleep over. It comes in three pieces: a head and two hands, so you can move them about to create the look that you want.

Pick your favorite spooky OS X Mac-o-Lantern pillow. Choose from “Count Macula”, “Spooker”, Mac-o-Lantern and “Finderstein.” The perfect Halloween companion for you and your Mac. These are available from Throwboy on Etsy for $39.

The blood puddle pillow is the ideal way to start your Halloween morning. I would suggest substituing this pillow for your regular pillow while your wife is sleeping. She’ll wake up to a surprise and start Halloween with a nice healthy scare. It’s not everyday she wakes up next to you laying in a puddle of blood.

These go well with the Roadkill carpet. These are made by artist Keetra Dean Dixon. And though it may be a bit late for this Halloween, there’s no reason you can’t be ready for next year.

This guy is kinda cute, but at night I think he might scare you and whisper to you in your sleep, telling you to plug in gadgets so he can feed and grow, using the energy to spin a web and eventually encase you in a cocoon. It will take up to 6 USB gadgets and it’s seventh leg goes to your computer. I guess some guy who really likes bugs had some spare time on his hands. It’s made from fabric and wires and is a great scarecrow to keep your kids away from the computer.

If you happen to see a guy or gal wearing a wrist knife like this and approaching you on a darkly lit street, you’re gonna wanna run like hell. I think it’s safe to say that this thing could probably gut you real fast.

What could be scarier then than this? The price. At under $40, any psycho stalker, or goth D & D misfit can afford one and take to the street. See, this kind of thing here is why we need Batman to be real. It’s just crazy. You can also get one in dragon or skull form.

I may have missed a memo, but last I checked Halloween was still a long way off. These should have surfaced around October. But hey, I guess even the Ghostbusters need a mouse that fits their style, though this ghost was obviously based on the Scream mask.

The mouse features an advanced 3-button optical scroll technology to provide you with high precision control. 800 dpi optical sensor. All the usual specs of a mouse. Aside from looks, I think the one thing that might make using this mouse a tad awkward is the ghost’s tail, unless your hand conforms to it. Scare up one of these for $12.
