Wireframe Cube by Michael Hobizal

Really cool CSS cube transformation. Make sure you check out the effect on hover! It's almost too much for my sick Dayquil filled mind to handle.

Tetris Background by Jason Brown

Tetris done in canvas. Need I say more? Be sure to check out all the work that went into that JS file. There's definitely a lot that a canvas newbie (me) can learn from.

Cool Future-like Interactive Dropdown by AaronChuo (小狂)

A Sass built sci-fi menu, completely JavaScript free. I recommend playing this in the background.

A fractal animation by Louis Hoebregts

A vector fractal animation made with RaphaelJS. The JS looks a bit daunting at first, but it is worthwhile to look into how this is done. The techniques behind fractal creation in programming are generally simple concepts like recursion that produce fascinating results.

Swinging Lightbulbs by Brandon Lawrence

Pure CSS swinging lightbulbs. My mind can completely grasp fractal generation, but CSS transformations are for some reason beyond me. It's easy to see its power though so definitely a good skill to have under your designer belt.

error 404 glitch by Kai Waddington

Another great example of the power of CSS and Sass. Switch the background to black and you'll feel like you're 20 rounds deep in the P.T/Silent Hill trailer.

Grid by Guillaume Gouessan

As someone still getting started with Canvas, this just blows my mind that such little code can produce something this complex.

Memory Game by Nate Wiley

Awesome memory card game built with easy to follow JS. I used to play this game at my grandma's house with real cards and it's a lot easier when you can just cheat by peaking under the glass coffee table to see the card faces. Still have a perfect memory though. ;)

Kruskal Minimum Spanning Tree by Nicolas Barradeau

Make sure you click rerun for this amazing implementation of Kruskal's algorithm for finding the minimum spanning tree of a graph. In other words, this will find the minimum weighted path that connects all vertices in this graph. If you're not familiar with the algorithm (or graph theory in general), looking through the code here probably won't reveal much. But if anyone is interested, the algorithm is surprisingly easy to follow in a theoretical sense and we would be more than happy to write up a quick tutorial on how it's done.

Vapor Trail by Artem Zubkov

Another awesome example displaying the power of Canvas. Definitely don't turn every option up to the max and freeze your computer like I did..
