With the sixth flexing he disappeared entirely. With each successive flex, more of his tie vanished into the flexagon. This morning one of our fellows was sitting flexing the hexahexaflexagon idly when the tip of his necktie became caught in one of the folds. Since then it has been a source of continuing wonder.īut we have a problem. It took us only six or seven hours to paste the hexahexaflexagon together in the proper configuration. I was quite taken with the article entitled ‘Flexagons’ in your December issue. The first was from Neil Uptegrove of Allen B. When Martin Gardner wrote about these bemusing creatures in his first column for Scientific American in 1956, he received two letters. What has become of the 2s?Įxploring the properties of this “hexahexaflexagon” offers an intuitive lesson in geometric group theory: Now the top of the figure can be prised open and folded down to produce a new hexagon - this one with 1s on one face and a surprising blank on the second. Fold down two adjacent triangles so that they meet, and then press in the opposite corner to join them. With some adroit pinching this hexagon produces some marvelous effects. The resulting hexagon should have six 1s on one side and six 2s on the other. You should be left with one blank triangular tab that can be folded backward and pasted to another blank panel on the opposite side. Then fold the resulting figure backward at cd. In October 2011, he played a new four-channel work for computer and hand-held air horns, titled Tetralemma + Tetrafluoroethane.Create a strip of 19 triangles like the one above ( printable version here) and fold the left portion back successively at each of the northeast-pointing lines to produce a spiral: Image: Wikimedia Commonsįold this spiral backward along line ab: Image: Wikimedia Commons Performing as EVOL in February 2016, he premiered Opus17aSlimeVariation#8-a reinterpretation of Hanne Darboven’s Opus 17a. Roc Jiménez de Cisneros has presented his work twice before in the Lampo series.

Since 2013 he has been pushing this spatial-material approach to music in different ways, originally drawing connections between holes and music, then extending that to folds and folding, to produce a series of pieces, talks, light installations and publications that propose a reevaluation of musical phenomena as volumetric and topological structures. Much of Roc’s work is rooted in an interpretation of music in morphological terms: mutated forms, spatial relationships and elasticity, both in a metaphorical sense and a literal one.

Their recordings have been published by record labels such as Diagonal, Editions Mego, Presto!?, iDEAL, Hypermedium and others. Their work considers processes of deformation applied to post-acid house culture. Roc Jiménez de Cisneros (b.1975, Barcelona) is part of the computer music group EVOL together with Scottish artist Stephen Sharp.

Wonky bass lines and drum patterns get continuously bent, flexed and contracted in unexpected ways. The work is Roc’s weird love letter to the tracks, producers and sounds that shaped dance music, turned into a stream of awkward locked grooves and algorithmically-churned acid motifs. Six Hexaflexagons for Chicago is a new audiovisual piece from Roc Jiménez de Cisneros and a direct homage to the history of early Chicago house music, performed here in an early Chicago house.
