Spaceblooms. Computer artwork of fluutmad (red) and wasphere (green) spaceblooms, both part of a fictional 23rd-century range of edible space flora (xflora). Spaceblooms combine nanotechnology and biotechnology. Several metres in diameter, they drift or move through space, feeding, growing, reproducing, and being harvested for food and other products. Fluutmad and wasphere move using solar sails. Spaceblooms were created by Canadian graphic artist and writer Martin Naroznik using 3- D software programs. Spacebloom: A Field Guide to Cosmic Xflora was published in 2004. There are also plans for an exhibition.
