So my current project for Uni is to design a working user interface project for a game using Powerpoint, to demonstrate a main menu, in-game user interface, pause menu etc. We had to come up with a vague idea of what sort of game our UI was for, so I came up with a simple sidescroller for a tablet, involving monkeys. I also decided to do some (kinda rough) artwork for this to make it a bit exciting than clicking around some menus.
The UI itself is pretty much finished but I'm working on a video playthrough of it that I'll post sometime soon, for now, here's some of the art work that I did for it. They're not too fancy but I think they're a fair standard for the length of the project :)
