Some concept designs I've made on Photoshop.
This is a Keyboard Tester I've been working on. The finished application should show a circle, which moves left when the left key is pressed, then snaps back when the key is released. It should do this for all the arrow keys as well as turning red when the r key is pressed, green when the g key is pressed, blue when the b key is pressed and a random colour when x is pressed. It will also grow when space is pressed and turn to a square when shift is pressed.
This project is a work in progress, when it's done it will be a banner advert for a fake energy drink.
