I'll take any excuse to play around with a fun iPhone app. Have you tried out Diptic? It makes it easy to combine photos into a collage on-the-go—even for someone who gets confused by her microwave.

After an evening full of excitement it's hard to choose which photo will truly capture the night's events. But with Diptic you don't have to pick just one! You can collage multiple images from your iPhone (or whatever device you're a fan of) using frames, border colors, and much more. Once you've mashed-up your favorite photos (sunset, concert, bar crawl, anything), you can share them with those who missed out on the fun. Diptic allows you to post your perfectly stylized images to Facebook, Twitter, Flickr, Tumblr, Posterous, and if you're slow to the social media train you can of course use email.

And now there's an even better reason to try this app. You could win ten tees from Junk Food Clothing (like the one pictured above) just by entering the Diptic "Show My Style" contest! Simply pull together a stylish outfit and post your photo to Twitter or Instagram with the hashtag #ShowMyStyle.
