I think it would be nice to have a design language:

  def port 0,0 100,100:
    L 10,10 90,0 90,70 70,70 70,90 20,90 20,70 10,70 10,10
  
  def bank 0,0 400,100:
    port 0,0 100,100
    port 100,0 200,100
    port 200,0 300,100
    port 300,0 400,100

  def router 0,0 1100,200:
    port 50,50 150,150
    bank 200,50 600,150
    bank 650,50 1050,150
    
  router 0,0 1100,200

I was thinking it would be cool to have an "about" page in openwrt showing your router with all the ports labeled in svg. Should be simple, but I couldn't figure out luci.
