Couple suggestions, that would make it fun for youtube videos: 1. Let the user change the background, and add letters/text. 2. Ability to add sound effects 3. Rube golberg style components that could be triggered by the circuit. 4. Render/Simulate real leds. 5. Add a gallery ... do you have a gallery of circuits others created? 6. Also, if you could save and output a video file of the circuit. It would make it easier to include for things like youtube videos, and possibly do animated logos and marquees using this simulator.
