Shoes.app :width=>600, :height=>450 do

  button "Slow" do
    1.upto(60) do |theta|
      append {line 0, 0, theta*10, 450}
    end
  end

  button "Fast" do
    append do
      1.upto(60) do |theta|
        line 600, 0, theta*10, 450
      end
    end

# I kind of like calling append a lot because its fun to watch things being
# drawn, but the performance on my machine is prohibitive. Is anyone else
# seeing similar things?
