I've used this approach for slides and websites. Any time I see a great design, I'll take a screenshot and save it in a folder called "PowerPoint/Web Ideas". I'll even include some shots from typography style music videos. Then whenever I have some free time and am bored, I'll try to recreate it in PowerPoint. Most of the designs are TOO MUCH for teaching slides, but its fun practice since making slides is sort of my job. But the practice gives me a better understanding of what I can do with presentations, building templates, messing with color theory, etc. There's a science/art to making a good lecture presentation and I'm enjoying the artistic expression, while still being educational task.
