Plaid huh? We are definitely viewing the issue at a much deeper level than Tegmark's description of the frog (or anything else) as an intertwined "bundle of pasta!" (How I do love his paper on multiverses, A-G!) Amazing, but I can imaginatively visualize this "plaid," too. Maybe call me nutz, but the visualization enables one to "see" that physicality is essentially geometrical.
After your suggestion of an extra time dimension, I've been doing some rereading of Tegmark, Grandpierre, Penrose, the Space-Time-Matter consortium and Cumrun Vafa. It is increasingly clear to me that the key to the riddle is geometric.
