I have no hobbies, that’s too lightweight.
Everything I am interested in or create is a major production, to be taken very seriously.
Multimedia, computer games, the Macintosh, design (profession), fractals, 12-16th century music, ethnic music, eclectic music such as Tangerine Dream and Jan Garbarek. Choral music and creating 3D landscapes using fractal textures. Middle Eastern history and so on.
I like spacing out using visualiser types of fractal VJ software. (LSD for Aspies!)
I would say crafts, but my eyes are not good enough for the tiny stuff I used to do in the past: knitting complex challenging patterns, celtic embroidery, cross stitch, crochet and very fine drawing of surrealistic landscapes and painting Vasarely like designs.
