Fell free to fork into your own extension !
Use Bazaar or install manually with composer:
composer require clarkwinkelmann/flarum-ext-carving-contestThe perfect extension for Halloween
tankerkiller125 a bit late though, because it was the subject of my livestream tonight. Hopefully it will still be compatible next year 
Also, it's not complicated to replace the pumpkin with something else 
Ah man, you were too late. Guess I can use this next year. Good job, though, neat idea.
clarkwinkelmann Yes! I may replace the pumpkin with something that can be used year round. 
Ralkage This is exactly what I was thinking, I think the Flarum forum should host a Christmas tree contest or something of that nature, even better we could possibly modify the extension so that you can choose multiple colors and just use a blank white image as the background so it's a full blown drawing competition.
tankerkiller125 I ended up using this at my meditation forum with a blank white image so that one can do quick little zen drawings like an enso. I'm the only one who uses my meditation forum though. 
But, one day someone might join and get a kick out of this.
Version 0.2.0 released with the ability to sort by either date of upload or number of likes.
Also improved performance, added pagination and preloading, improved the likes button design and made the modal work to see the list of all users who like when it goes into "and n more".
Version 0.2.3 released with Flarum beta 16 compatibility and a new switch between painting and carving mode.
You can watch me update the extension in today's live stream.
If you want to use this new mode to paint on eggs, I have already prepared an image (from a CC0 license) with the correct size. You can use it to replace assets/extensions/clarkwinkelmann-carving-contest/pumpkin.jpg
I have released version 1.0.0 with support for Flarum 1.0+
When I see extensions like these I imagine indian festivals 
clarkwinkelmann I installed this extension yesterday and we had almost 70 submissions in just 6 hours, this was one of the funniest moments on my forum 
https://forum.fibra.click/carving-contest (you probably won't get most of them since they're jokes related to the topic of the forum)
Thank you! 
P.S. we also had cheaters
matteocontrini maybe in a future update I should add a feature to prevent "cutting" outside of the pumpkin
I probably can't do anything to cutting the entire inside of the pumpkin though
You could also "cheat" to submit more advanced designs by editing a black and white picture in an external software and then substitute the base64 image in the submission with your external image

That's what they did in the above screenshot indeed!
matteocontrini oh! I wasn't 100% sure. The circle looked a bit too perfect but the rest seemed like it could have been done by hand if someone had a lot of free time
How can I change the pumpkin image?
Leonart you can find and modify it in the assets folder of your forum. I don't remember which sized and file formats are valid though. If you use the same as the pumpkin it's the safest.
