Update | Umbrella Revolution: more designs on Hong Kong’s protest movement

Through tear gas and the sweltering sun, umbrellas have been an indispensable tool for Occupy Central protesters in the streets -- becoming a new symbol of protest for a more democratic Hong Kong.

As the civil disobedience movement entered a second day on Monday, logos for the "umbrella revolution" or "umbrella movement" began spreading on social media. 

Kacey Wong, an artist and assistant professor at Polytechnic University, shared images of an umbrella in fiery red-orange, from the Resident Evil films, in an attempt to inspire other artists to come up with designs.

Another logo shared by netizen Ger Choi showed the outline of a white umbrella, above which hovered a yellow star in a halo of green and blue.
