Nerds around the world, sharpen your pencils and shine your calculators — Pi Day is upon us again. Every year, 3/14 is a day we set apart to celebrate Pi, the mathematical constant describing the ratio of a circle’s circumference to its diameter, because the first three digits are 3, 1, and 4. Last year, the U.S. House of Representatives passed a non-binding resolution (H.RES.224) recognizing the holiday, which is also Einstein’s birthday. That’s all the justification I need to party.

Because this year’s celebration, isn’t until next Sunday, we have plenty of time to get our pi-parations in order. Visit PiDay.org to learn more about the greatness that is Pi, or send your most deserving friends an e-card. Stock up on your Pi apparel, like this T-shirt from Neatorama or hoodies and housewares from ThinkGeek.

And get those Pi-cecubes a-chillin’ for their signature Pi-Tini, because once Pi Day eclipses, we’ve got 365 long ones until it’s here again. (Unless, of course, you count Pi Approximation Day on 7/22.) And if you need a little Pi year-round, check out Katie D.’s Pi dresser find for some furniture inspiration. — Sarah C.

In my humble opinion, coffee tastes best out of porcelain. It retains the heat well and, more importantly, makes me feel classy. But my favorite porcelain mug doesn’t fit in my car’s cup holder. What’s a commuting, coffee-crazed gal like myself supposed to do? Get myself one of these double-walled porcelain commuter cups from Vessel drinkware, that’s what. They’re heat safe to 170°F, have a nifty silicone lid, and are microwave safe. But best of all, they’ve got fun and modern designs. If you’re a fan of the original Batman TV series, the Pow! tumbler should appeal to your love of onomatopoeia. If your taste is less bat and more owl, then Tough Little Owl is for you. But my favorite of all is the Mustache Chart, simple white with a handlebar mustache — and a handy guide to other styles. Classy with a touch of kitsch, and totally affordable at $15.99. — Megan B.

True story: when I was little, the worst trouble I ever got into was when I was caught stealing cookies from the cupboard. It’s that kind of dedication to my sweet tooth that makes me crazy about the Dunk Mug (and gave me the four cavities I have to get filled next month, yikes). Designed by my new idol Dominic Skinner, the Dunk Mug has a built in shelf for discreetly housing a small cookie stash. The cookie shelf (or “biscuit shelf,” if you’re as charmingly English as the site) should be turned away from you as you drink so that nothing falls into your lap as you sip your morning caffeine. Don’t worry: there are both left-handed and right-handed mugs available since sugar junkies don’t discriminate! — Katie D.

How did I miss this incredible idea from Not Martha?! These tiny gingerbread houses are made to be perched on the edge of your mug of hot cocoa (or whatever you may be drinking). These are too cute to put away for a whole year, so I was thrilled to see Not Martha had success making these houses out of sugar cookie dough as well. While gingerbread screams holidays, sugar cookies are welcome in my house all year round. — Erica P.

Designed by skateboarding San Francisco native Joey Roth, the Sorapot is a marvel of form-meets-function. It’s made from stainless steel, Pyrex, and natural silicone, and is more a work of art than a simple drink dispenser. Thoroughly modern and thoroughly unfussy, the Sorapot is worthy of its $200 price tag (as well as the 20-minute video of its designer discussing its attributes on the Sorapot page). — Katie D.

After I posted a link to Saveur’s Tom and Jerry recipe, I couldn’t get it out of my head. It just seemed so elegant and warm for the holidays, especially as we were having Christmas breakfast with two friends, so I decided to give the recipe a whirl. I think the drinks turned out exactly right, but not without a lot of effort.

First, separating eggs: I don’t find this that difficult (I just do what my mom taught me, which is to plunk the yellow back and forth between the shell halves while the white drains into a bowl) but I did that classic thing where you accidentally drop the yellow into the white, and it breaks, and then you start over.

Second, reading comprehension: All my ingredients are measured out, add the two cups of rum to the batter….hmm, that’s not thickening as promised. Oh, you said two TABLESPOONS of rum? My mistake. Dump the batter, and start over with the egg separating thing… Read on, if you dare. (more…)

Just in time for the holiday party season comes the witty On the Rocks ice cube tray. I spotted them at Perpetual Kid, where they’re currently out of stock, but you can also find them at Amazon.com. The tray comes with several different colored swizzle sticks to ensure that you and your fellow revelers will be able to tell whose drink is whose (without those silly glass charms). — Katie D.

I don’t have much space for a bar in my apartment, so I went with this tray setup. Then I saw this awesome hanging bar and began to dream of a bar makeover. Just today I spotted the Coco Mini Bar and I’m officially in full-on jealousy mode. Leonhard Pfeifer brings us great design (and an even better tagline—”a mini bar so delicious you’ll want to have it home for a drink”) with his Mini.BarBoudoir series. I’m particularly smitten with the Coco Mini Bar design which uses classic Chanel nail varnish as the hand-painted finishing touch. According to Design Milk, the colors Pfeifer uses are Chanel No. 159 Fire Red, the classic movie star shade, and No. 18 Rouge Noir (worn by Uma Thurman in Pulp Fiction). The bar is part of a collection of eight limited edition pieces. — Erica P.

I couldn’t help but chuckle at the design of these Teabag Mugs from Bailey Doesn’t Bark. Check out the Bailey Doesn’t Bark Blog for a sneak peek at the process of making these unique cups. While $36 seemed like a lot to pay for a mug, once I saw how much work goes into making each one, it didn’t seem like too much. I think a set of two would make a great housewarming gift. — Erica P.

We got an email the other day from the creative mind (and fingers) behind the Daisy Janie blog pointing out this easy tutorial for a paper wine gift bag. For those of you that are handy with a grommet press and have access to some colorful prints and ribbons, this how-to could be the answer to your upcoming holiday needs. It’ll turn a simple bottle of Yellow Tail into something to treasure.
