ランダムで模様作るよ

前提：

gem install geo_pattern --no-ri --no-rdoc

gem install color

require 'webrick'
require 'geo_pattern'

random = Random.new(20)
server = WEBrick::HTTPServer.new({:BindAddress => '0.0.0.0', :Port => 3000})

trap(:INT){server.shutdown}

server.mount_proc('/') do |req, res|
  range = 0.0..1.0
  col = Color::RGB.from_fraction( random.rand(range), random.rand(range), random.rand(range) )
  pattern = GeoPattern.generate(col.html, patterns: :plaid, base_color: col.html)

  content = "<div style=\"background-image: #{pattern.to_data_uri};min-height:768px; width:1024px;\">"

  res.body = content
  res.content_length = content.size
  res.content_type = "text/html"
end

server.start
