Tools for a revolution can be as simple as the items lying around your home. A young man at Hong Kong's pro-democracy demonstration pulls out a few items from his knapsack: an umbrella, a towel, shorts and his smart phone. Throw in some Post-it notes and you're on day seven of the demonstrations.
There is now a wall of colorful Post-it notes in Admiralty, a business district, that has seen the largest protests. Demonstrators are answering the question, "Why are we here?" Many of the answers are along the lines of "I love HK" or "I want true democracy."
