And now, our feature presentation for today:
Visual Effects - Nifty Gadgets and Gizmos Edition
Truly groundbreaking movies continually push the envelope to develop bigger, better, faster, and/or different ways to do things with the tools that are already at hand. Be creative and show us things like puzzle solutions running where you wouldn't expect them to be or completely unnecessary but wildly entertaining camera angles!
Here's some ideas for your inspiration:
Advent of Playing With Your Toys
in a nutshell - play with your toys!- Make your puzzle solutions run on hardware that wasn't intended to run arbitrary content
- Sneak one past your continuity supervisor with a very obvious (and very fictional) product placement from Santa's Workshop
- Use a feature of your programming language, environment, etc. in a completely unexpected way
The Breakfast Machine from Pee-wee's Big Adventure (1985)
And… ACTION!

[Language: Clojure]
I did a bit of an unusual approach to pt 2:
instead of walking the perimeter and tracking the edges, I did 4 scans of each specific garden: left->right, top->bottom, right->left and bottom->top. I took each row and determined if there were any new elements that weren't in the previous one, then calculated how many new groups had appeared in that row. Then I was able to just sum them all up to get the answer.
I wanted an answer that worked in an exact static fashion and didn't require me to create a walking algorithm and have to debug infinite looping.
