Last week we put out a call for the best do-it-yourself Halloween costumes lifehackers could come up with, complete with instructions and images. As usual, you did not disappoint. Submissions ranged from the ironically funny Blue Screen of Death to whippin' it good with Devo; all creative, all completely homemade. After the jump, a ghoulish gallery of horrifyingly hip creations.

Calling all crafty DIYers with just a naughty twist of scary! Next Wednesday is Halloween, and we want to spotlight your best DIY Halloween costumes so we can rip them off for our own party. Anything from cute to somewhat disturbing is fair game, as long as it's homemade. The more clever, easy and cool it is, the better. Impress us! Email your high res costume digital photo to [email protected] with the subject line DIY Halloween Costume. Ideally, your photo will be 600 pixels wide so we can admire the details of your handiwork, and you'll include information on how you made it, with a materials list and construction details. We'll publish the best submissions this weekend in preparation for the big day. Have fun and get to digging up those great costume pics!

For some people, desktop media player applications are a very personal thing. Rather than living life in the vanilla world of iTunes and Windows Media Player, these music lovers prefer media players they can tweak, customise, and personalise to their heart's content. Today we're taking a look a look at user-submitted pictures of their always impressive and often enviable desktop media players. Hit the jump to take a look, and if you see one you like, find out how they did it.

From foobar2000 and Media Monkey to Winamp and beyond, there are tonnes of killer media players available with an emphasis on customisation. For this Thursday's screenshot show and tell, we want to get a closer look at your tweaked-out media players. Interested in sharing your jaw-dropping media player application—be it Windows, Mac, or Linux? Hit the jump for submission details.

After taking a close look at everything you carry in your go bags, it's time to pare things down and see exactly what the pockets-only crowd deem worthy of their coveted lint-space. From the entirely minimal to the surprisingly bulky to (*gulp*) handguns, hit the jump to take a closer look at what Lifehacker readers are carrying in their pockets.

We got all up in your personal space a few weeks back in our Go Bag Show and Tell Parts one, two, and three, but in case you missed any of the submissions or wanted to take a second look at what your fellow Lifehacker readers carry around with them when they need to get things done on the go, we're rounding up every submission into one master gallery for your browsing pleasure. Hit the jump to take a look.

You showed us your go bags, and frankly, they were fantastic. But many of you pointed out that the whole go bag business seemed overwhelming—that you're minimalists who've stripped down your needs to whatever you can fit in your pockets. So for next week's show and tell, we want to see what you're packing in your pockets. Photo by janerc.
