This is clearly a case of apophenia or pareidolia. It is a popular method for conspiracy nuts to find symbols where none exist. They seem to ignore the rest of the stage that extend out from the bottom of the ribbons. To create the symbol you have to cut those out of the stage. It is bizarre that Hyatt is so stupid as to go along with this.
