It's not a cross. Some people just build giant lower case "t's"
"giant t's"
Which sort of reminds me of one other proposal, namely that the cross be set up so that it recognizes religions in proportion to the local population's membership in each. We'd mount the 'wings' on hinges, then lower them for a portion of the day that was equal to the percentage of local residents offended by a cross. We figured the lowering would be from 3:12 to 3:14 each morning.
