December 1st is one of several Pie Day holidays. You can celebrate by baking and eating pie, or by looking at these. (And you can celebrate again on January 23rd.)

1. Deadpie

If you love Deadpool and pies, then you might want to try your hand at making this masterpiece created by Dixonverse user Lurker’s friend Anna: a key lime pie adorned with the anti-hero’s famous mask made from chocolate sour cream topping, Oreos and strawberries.

2. The Cake is a Pie

Fans of Portal are well aware that the cake is a lie, but have you ever considered that perhaps it is only a lie because the cake is a pie? Admittedly, this pie by Geeky Mormon Woman only looks like the famous nonexistent cake from directly overhead, but that's because it's a pie.

3. Millennium Falcon

The great thing about thin pie pans is the same thing that can make them so annoying when you pull them out of the oven – they bend all too easily. Amy Ratcliffe of Geek With Curves found this to be ideal, though, when she set about making a pie that looks like the Millennium Falcon, which required the pie pans to be bent into the shape of the ship. (She went with an apple filling.)

4. Star Wars

Don’t have quite the crafting skills to make a Millennium Falcon pie crust? Well, you can always follow in the footsteps of Olds Ninety-Eight writer Cathy who turned a regular blueberry pie crust into something a whole lot more awesome and geeky with a few Star Wars cookie cutters and a little extra pie dough.

5. Apple iPie

If you know someone who will only eat apple pies because they want to stay loyal to their favorite brand, then consider blowing their mind by recreating this amazing creation by Evil Mad Scientist Labs.

6. Pie-rate Ship

If you like pirates and puns, then you’ll be happy to know that there are all kinds of great pies combining the two. This structurally-impressive Pie-rate Ship design by Susan S. of Diamonds for Dessert actually looks like a pirate ship. If you’re wondering what kind of a tin she used to get such a great boat shape, a thin bread pan can easily be manipulated into a boat shape.

7. (Pi)rate Flag

Need a good design to put on your Pie-rate Ship sails? How about this great (Pi)rate skull and cross pis logo created by Instructable user emitchell314 as part of his entry into the site’s yearly Pi Day contest.

8. Pi-rat

Of course, if you do make a Pie-rate ship, you’d better watch out for stowaways, particularly those pesky Pi-rats, like this one that hid inside of Instructable user S-creek’s Pi Day contest entry.

9. Pi Shaped

For a more traditional tribute to Pi Day, you can always follow Serious Eats’ guide to making a simple pi pie.

10. All Numbers

If you really want to celebrate the wonder and irrationality of pi though, it’s probably better to follow A Periodic Table Blog writer Shannon’s instructions for making a number-filled pie with a crust that features the first 20 or so digits of pi. Now that’s a thing of mathematical beauty.

11. Venn Pie-agram

Can’t decide between a strawberry or a blueberry pie? Perhaps you should make a chart extolling the virtues of each. Then perhaps you, like Reddit user HungryHungryHippy, might even end up turning that chart into a Venn Pie-agram that allows your guests to come to their own conclusions on the similarities and differences between the berries.

12. Piception

Can’t choose a pie flavor? Perhaps you could go all Inception on your pastry-baking and make a pie within a pie within a pie. Of course, if you have real skills, like Instructables user Beanie10, you’ll also find a way to incorporate an empty limbo space in your pie, the pi symbol inside the filling, the word “Piception” along the side of the pie and a maze on the crust.

13. Pie-cosahedron

If you are able to master the Piception challenge, perhaps you should try your hand at the amazing twenty-sided pie created by Instructables user turkey tek. How do you even begin to create a monstrosity like this? Well, the first secret is a handmade twenty-sided pie pan; the second secret is to disassemble the massive pan into individual sections before baking.
