Kids love to create their own little world whenever they can. Leave any child alone with a sheet and two chairs for five minutes, and they’ll build their own Fortress of Solitude, far far away from the Land of Boring Grown-Ups. We know that kids thrive when given their own space; there was even a little boy named Max who became a king.

Play forts are fun, but when you’re looking for something a little more permanent than a cardboard box, check out Modern Cabana. They create pre-fabricated buildings using sustainable materials like bamboo flooring and recycled denim insulation.

Recently, they’ve begun offering the “Kiddo” model. Housed in a compact frame (48″ x 65″), the modern, sleek structure includes tons of natural light, a multi-paneled door, chalk paint interior walls, a fold down table, and even a paper roll art station.

Available for about the same price as that HDTV you’ve been eyeing, it’ll give your kids years of enjoyment, and it might even let you reclaim a little bit of your own home.

It used to be that the art world was just for those with private jets and Swiss bank accounts. Luckily, thanks to the magical powers of the internet, it’s easy to get a crash course in art collecting.

But wait, why art? Well, besides being nicer to look at than peeling wallpaper, it produces all sorts of benefits: art boosts kids’ imagination, improves their sense of craftsmanship, and even helps with problem-solving. And one of the easiest ways to inspire an early love of art in your kids is by surrounding them with colorful and vivid imagery.

Created by New York gallery owner Jen Bekman, 20×200’s stated mission is to make art available for everyone. Every Tuesday and Wednesday, they announce a new “edition” on their site, featuring works by both well-known and up-and-coming artists.

For a mere $20, you can pick up one of their 8″ x 10″ prints. The catch is that there’s only 200 of each for sale (hence the site’s name), so once they’re gone, they’re gone for good. Too small for you? Bigger sizes are available—11″ x 14″ and 16″ x 20″—for bigger prices. Art featured at 20×200 covers a wide range of styles, from travel photography to quirky sketches.

Similarly, Thumbtack Press has affordable prints by dozens of artists and illustrators, who tend to lean towards the comical and whimsical side of things. If the idea of picking out art is overwhelming, Thumbtack conveniently offers a few curated collections (“Kids’ Prints,” “Tony’s Favorites”) to get you started.

So come on, give your kids something new to look at. And no, your old concert posters don’t count.

Sure, everybody knows about Kermit, Miss Piggy, Fozzie, and the rest of The Muppet Show’s big-name stars, but let’s salute the unsung heroes of the show: the Whatnots. These hard-working Muppets were the wacky-looking extras that appeared in the background of various skits. Granted, they lack the glamour of the celeb-Muppets; Whatnots are truly the working man’s Muppets.

While Animal and Gonzo were up to who-knows-what in their fancy trailers, Whatnots were getting chased by Muppet chickens and pelted by Muppet eggs, just to earn a few seconds of screen time. They weren’t in it for the fame, they only wanted to make you laugh. Now is your chance to pay them back, by bringing one home.

The Muppet Whatnot Workshop site lets you create your own custom Whatnot, with a wide selection of body types, eyes, noses, hair styles, and clothing options to choose from. Of course, you can preview your creation, and keep changing it until you get it just right. Then, just a few days later, you’ll have your very own Whatnot. But please, treat them with the respect and dignity that these entertainment veterans deserve.

Do you like to talk about all the home projects you’re going to finish someday? It’s probably a really impressive list — surely, your kids will just love that dream tree house. Instead, there’s rain gutters that need cleaning, lawns that need mowing, and that pesky job where they expect you to show up five days a week. Oh, and you don’t have any trees in your backyard anyway. What to do now?

Face it, it’s time to call the experts. The folks at Daniels Wood Land create incredible tree houses, all featuring their signature crooked windows that make it look like a team of drunken elves got loose in the workshop one night.

Based on the motto of “Tree Houses that come with their own Tree!” the Daniels Wood Land creations use giant recycled logs in nearly all their designs. Available models include the “Scallywag Sloop” (pirate-themed), “Country Playhouse” (Huck Finn-era shack), and even custom Castle and Tropical themes.

And of course, each tree house can be outfitted with as many additions as your wallet can handle. Items like tire swings, fireman’s pole, rock climbing wall, trapeze bars, and a swinging bridge are all available for a few more bucks. While you’re at it, pick up some extra snacks too, because you’re about to have every neighborhood kid start begging for a playdate.

When was the last time you had time to paint a room in your house? Exactly. Since it can be a small victory just getting the kid dressed in the morning, your walls might be looking a little neglected these days.

If only there was a simple way to completely change the look of a room in about fifteen minutes, right? Billing itself as the “world’s first removable wall graphic company,” BLIK is a great way to add a little fun to any room. With BLIK, all you need to do is peel off the vinyl decals and start applying it to your walls. And when you’re ready for something new, they’ll peel off just as easily.

With over 200 stylish designs, BLIK is sure to have something that everyone in the house will enjoy. Dad favorites include Donkey Kong, Space Invaders, and Super Mario – the classic video games designs transform your walls into giant arcade screens. Kids are sure to love all the animal designs that’ll turn their rooms into mini zoos, full of giraffes and elephants. For art lovers, BLIK has licensed designs from Ray & Charles Eames, Keith Haring, and Threadless to create even more great options.

Don’t worry, someday you’ll actually get a whole weekend to work on that home project, but for now, there’s BLIK.
