Happy Halloween, everybody.

This time of year brings out a lot of creativity, whether it's making your baby an amazing costume, dressing up as Shepard Fairey's iconic 'Hope' poster, or turning your house into a Halloween light show to the tune of Gangnam Style.

But one area where creativity really shines at this time of year is in the world of modifying pumpkins (like the pumpkin/watermelon version of Teenage Mutant Ninja Turtles villain Krang by artist Mike V, above).

Here's a roundup of some of the best pumpkin-related stuff we've seen online in the lead-up to today.

How To Carve A Pumpkin. With A Handgun.

There's something weirdly mesmerizing about this video of YouTube user Hickok45 "carving" a surprisingly accurate face for this pumpkin using nothing but a Colt pistol.

Stick around until the end to see what happened on the side you couldn't see.

The Badly-Restored Fresco Pumpkin

Remember that elderly Spanish woman who ruined a fresco in the Santuario de Misericodia church by trying to restore it?

Well, Toronto-based designer Graham Anthony has created a pumpkin tribute to the accidental genius of her work. Maybe someone will come along and carve a convincing picture of a saint over top? We hope not.

Maniac Pumpkin Carvers: Made-To-Order Custom Pumpkins

These guys have some serious carving skills - so much so that they've turned it into a successful business, with a huge volume of orders coming in during Halloween season. See how they do it above.

The Pumpkin Proposal

Is Halloween the new Valentine's Day? This guy thought so. His name is Chuck, and he decided to surprise his girlfriend Megan with a Halloween proposal.

He carved 'Will You Marry Me' into four pumpkins, then arranged them on the backporch of his girlfriend's parents' house.

After a dinner date, he brought her back home to find them lit up out back. The one with the arrow had a ring on top. Awww.

The 'Too Much Partying' Pumpkin

Saw this one on @LittleSimonB's Twitter. Sometimes the pumpkin party gets out of hand.

How To Build A Flaming Pumpkin (Safely?)

We're not going to recommend trying this one at home. But it does look pretty crazy.

According to DaveHax, the YouTube user who uploaded the video, it should burn for several hours, and all you need to put it out is water.

Pumpkin Pi: The Most Digits Of Pi Ever Carved Into A Pumpkin

Some records are just so obvious that someone had to break them eventually. Then there's this: Tai Star decided it was time to break the record for most digits of Pi ever carved into a pumpkin.

He managed to fit 66 digits of Pi onto this lucky gourd. If you really want to, you can watch him reading them all off in the video above.

The Cannibal Pumpkin

We saw this one on Instagram user wandawandoom's feed. Apparently it's a pumpkin-eat-pumpkin world out there.

The Tetris Pumpkin

It's a little awkwardly named (how do you even pronounce "Pumpktris"?), but that doesn't make this any less awesome. Nathan Pryor, who runs the Haha Bird blog, built a pumpkin with a playable game of Tetris inside.

The stem of the pumpkin functions as a controller, while the game itself is viewable through the holes in the front. Pryor hooked up a matrix of LED lights to the inside of the pumpkin, and wrote computer code to turn them into a playable video game.

No word on whether the kids in his neighbourhood will get off his porch now, please.

Mars Rover Curiosity: Pumpkin Edition

While the Mars Rover Curiosity is busy on the Martian surface, examining dirt samples and finding out how much the Red Planet resembles Hawaii, one NASA employee is paying tribute back on Earth.

Liz Warren works for NASA in Houston, and every year she carves a space-themed pumpkin. You can see her Curiosity handiwork above, and check out a gallery of her earlier work right here.

Saying Goodbye To Your Pumpkin

Sad as it is to admit, as of tomorrow, Halloween will be over. What happens to the pumpkins then?

A lot of them, sadly, will just be left to rot. But here are some more adventurous ideas for sending off our jack-o-lantern friends to the great pumpkin patch in the sky, courtesy Environmental Graffiti.

If you want to get medieval on your pumpkins when Halloween's done, you could build a trebuchet. It's a weapon that was used in the Middle Ages, and it's kind of like a giant slingshot.

Turns out there's a very competitive world of firing pumpkins out of trebuchets (and cannons, and centrifuges, and human hands). The Punkin Chunkin World Championships take place this year in Bridgeville, Delaware from November 2-4.

And the proceeds will go to scholarships for students as well as local community organizations. Pretty great use of a medieval weapon of war.

This one's pretty simple: all you need is a vehicle and an old pumpkin. There's something satisfying about turning your pumpkin into a tire-tracked mess of pulp.

Just make sure you clean up afterwards.

Gill Hurley, a farmer in New York, built this artillery-grade pumpkin cannon. It's powered by an air compressor, and fires pumpkins nearly 4,000 feet at about 600 miles per hour.

If you somehow manage to build one of your own, you'll need a lot of space to let fly.

Of course, you don't have to destroy your pumpkin. Check out this post for some ideas on other ways to reuse it.

Unless you have a pumpkin cannon - then you have to destroy it.
