I have just realized something. You can make absolutely anything better with the inclusion of an ATTiny13.
Think about it, you really can make any individual object better with an ATTiny13 and a little bit of creativity. This includes things rational people would not consider putting a micro controller in/on/around. For example:
-Rocks (ATTiny13 controlled mineral embedded photovoltaically charged lighting system)
-Pieces of Fruit (Use specific durations of blue LED light to keep it fresh)
-Lumps of Hair (A pager motor controlled by an ATTiny13 reacting to input and timer interrupts + some of those googley-eyes and you have a Dust Puppy)
-Small Birds (The possibilities are f***ing endless)
So, what would you make better with an ATTiny13?
