Drum Kit (Demo) 
Day 1 of 30 of Wes Bos' #JavaScript30 course. The requirements were to build a drum kit so that when a keyboard key is pressed, it would both play a corresponding audio element and scale/color the appropriate indicator on the screen.
I added touchscreen support and styled mine to look like the Rock Band 4 drum lane. I used some 3D perspective built into CSS transforms as well as some drop shadows for the glow.
I only used the provided starter HTML and the first couple minutes of the video that explained the requirements.
