random_giveaway.rb: Spin through some twitter handles and pick a winner

random_giveaway.rb

# Given a list of items in the 'entries' array, it'll spin through
# some random ones before settling on a "winner" which flashes.

# Yes, the code is terrible, I threw it together on the fly for a Twitter giveaway!
# See https://twitter.com/peterc/status/955955015126003712 for example

# Only dependency is curses, via "gem install curses"
