Web Development
This application has stood the test of time. I made this almost 10 years ago now. One of my first iterations of the Scaling Responsive Styling I use. Everything was conditional on the container div size, and the app built itself with javascript.
I still see it advertised during the show, from time to time. And they moved it to the front page of their website. Still ticking. Still Scaling. Still working on every device size. This may have outlived even my A-1 Steak Sauce site. That was close to 8 years. The death of flash sealed it's fate.
