# Description: Simple demo to showcase Redis PubSub with EventMachine
#
# Update 7 Oct 2010:
# - This example does *not* appear to work with Chrome >=6.0. Apparently,
#   the WebSocket protocol implementation in the cramp gem does not work
#   well with Chrome's (newer) WebSocket implementation.
#
# Requirements:
# - rubygems: eventmachine, thin, cramp, sinatra, yajl-ruby

# Recursive backtracking algorithm for maze generation. Requires that
# the entire maze be stored in memory, but is quite fast, easy to
# learn and implement, and (with a few tweaks) gives fairly good mazes.
# Can also be customized in a variety of ways.
