This Kaleider Spike Funnel was rendered from a photo of an old, frayed, weathered phone book.  The Funnel had been adjusted to 12 Spikes, and the Replicate Base Spike option was checked so that the other Spikes were copied from the single Base Spike, which was rotated to 345 degrees.  The end of the Base Spike was pulled outward.  Masking was toggled on with an Oval Shape and a dark gray background.
