After creating three of the “curves,” my code started to remind me of the opening credits by Saul Bass for Vertigo. So, I tried to place the fourth set of lines so that the curve echoed the eye that is synonymous with the Vertigo opening sequence. In addition, I set the background a darker red that also echoes the opening sequence. The sequence is embedded below:
