3 Rope Across by Oscar Munoz (Excerpt from Oscar Munoz Live) - Video Download

This is an exceedingly clever way of dressing up Professor's Nightmare. Rather than doing the classic trick in the same old way, Munoz shows two sets of ropes: one set has three ropes of equal length and the other set has three ropes of different lengths. Under test conditions and as visibly as possible, Munoz causes the sizes of the ropes to transpose.
