In addition to titanium, some artists are starting to experiment with other materials to create even more unique works of art. One recent example is a sculpture entitled 'Luminous Forms' by Chris Gilmour, which was made using over 80 000 LED lights. The sculpture takes on an amazing three-dimensional form, and is sure to dazzle anyone who sees it. Another interesting example is an art piece created by Christian Moeller entitled 'Titanium Rain', which uses 100% recycled metal scraps from various industrial processes. This piece is truly unique in that it's one of the few sculptures made from recycled materials that actually looks good!
