"Tricycle specializes in creating simulated carpet sample using paper. Currently, designers use real carpet samples in the design process, which is quite wasteful and costly. Tricycle uses a "digital tufting" software that simulates the actual placement of yarn in a tufting machine to create amazingly realistic images. Other alternatives, such as photography or texture-mapping over color fields, are not accurate enough to be useful,” claims Caleb Ludwick, market intelligence manager at Tricycle. Tricycle's paper samples require zero oil, and only about 5% as much energyand water as real samples, and are more likely to be recycled after they’ve been used. ::
