Photoshop turns 20 this year, and Adobe is celebrating with a search for the "Next Photoshop Evangelist," one among the legendary application's legion of multilayered fans. (Admit it. You have a Photoshop window open right now.) The company will select a primo proselytizer of all things Photoshop based on video submissions. Your mission, should you choose to accept it: create and upload to Vimeo a two-minute Photoshop video tutorial demonstrating why you should be the Next Photoshop Evangelist. Your video must use Photoshop CS5, a new Photoshop CS5 feature, and, to celebrate the 20th anniversary of Photoshop, incorporate the concept of "20" somewhere in the final image. The winner receives a fresh copy of CS5 Design Standard, a trip to next spring's Photoshop World, and the chance to demo his or her tutorial at the conference. Plus, all finalists will be showcased on the Photoshop YouTube channel. Ready to spread the Photoshop gospel? Entries must be received by Tuesday, August 24.

Healthy fast food with a side of social media. That's the idea behind 4Food, a new restaurant concept that will debut next month in New York City. With plans ranging from iPad-based ordering and in-store composting to the use of wholesome ingredients and printing personalized nutrition facts on receipts, 4Food aims to "de-junk fast food" in more ways than one. As for the food itself, the signature offering is the W(hole)burger—a donut-shaped, beef, lamb, pork, turkey, veggie, salmon, or egg patty that is filled with one of 25 "Veggiescoop" centers. Customers who register for online accounts with 4Food can create and name a burger and then receive 25 cents every time someone else orders it. Co-founders Adam Kidron and Michael Shuman hope to both build a community and stoke Facebook- and Twitter-using customers' appetites for self-promotion.

Looking to savor the last weeks of summer with fresh flip flops? Try a pair that will limit your environmental footprint: Feelgoodz. Described by company founder and owner Kyle Berner as "the most comfortable flip-flop in the world," the 100% recyclable and biodegradable sandals are made of all-natural rubber from Thailand, where Berner stumbled upon them during his post-college travels. And the eco-friendliness doesn't stop with the company's own products. As part of its mission to create a "Zero Flip-Flop Waste World," Feelgoodz has launched a pioneering initiative that collects and sends non-recyclable flip-flops to Kenya, where another company distributes them to villagers who make new eco-boutique items out of them to then use for resale. An additional upshot of this innovative upcycling? A $5 credit that you can apply to a colorful pair of Feelgoodz.

Ever dreamed of seeing your drawings come to life in a fierce battle of wills? Get ready for graFighters, an online fighting game that allows users to create their own avatars by uploading an image of hand-drawn characters directly from a laptop or mobile device. Sign up to be a beta-tester (or simply send in a drawing) and watch as your sketches transform into animated warriors, climbing the ranks as they challenge the drawings of others. "The game is not played with traditional buttons or combinations but rather with the strategic design and creation of the drawing itself," note founders Dave Chenell and Erik Cleckner, recent graduates of Syracuse University. The result? Nothing short of "a new genre of creative gameplay."

Where's the wireless? Wear this and know instantly. The Wi-Fi Detector Shirt is a standard black cotton tee with one geeky distinction: a glowing decal that dynamically displays the current wi-fi signal strength. A discreet inside pocket holds a trio of AAA batteries that power hours of signal-detecting fun, and all of the electronic bits are removable come laundry time. We think $19.95 is a small price to pay for avoiding the disappointment of powering up a laptop only to find oneself marooned in a wireless dead zone. Plus, wearers are bound to make friends at the airport. Whether you'll be forced to power down the shirt until reaching cruising altitude is another story.

Don't toss out those old Crayolas! Ship them off to the National Crayon Recycle Program, which has collected more than 55,000 pounds of unwanted crayons from schools, restaurants, and art supply hoarders nationwide. Founded in 1993 by LuAnn Foty, the initiative helps to keep the petroleum-based wax used to make crayons out of landfills and repurposes the colorful castoffs. Your old Burnt Siennas, Cornflowers, and Magentas will be reborn as Crazy Crayons, hand-crafted morsels of color that come in a variety of shapes. Ready to recycle your crayons? Just remember to leave the wrappers on, lest the sorters confuse Black, Midnight Blue, and Violet.
