I don't normally get excited about shower tile this soon after breakfast, but Moving Color tiles use that technology from my TARDIS mug twenty years ago (put in hot water and the TARDIS vanishes) to cause incredibly cool (well, warm) colour shifts during your shower. The Northern Lights line shifts on the Aurora Borealis pattern, Watercolours "closely resembl[es] the luminous quality of water color", and Tye Dye is dark through vivid bright coloured fractals. Available in a range of eight colours, the tiles are 10cm x 10cm and not recommended for people who get picky about everything matching everything all the time. [GT]
