Photo by Cathy MatusowHouston artist Dale Stewart died Monday at age 34. He was brilliant, and he was my friend for more than two years.Dale was fascinated by the world, and that made him a fascinating person. His obsessions were too many to count. He loved his family, adored his little girls Anna and Kate beyond all measure. He was captivated by spinning tops, engines, fans, records, record players, Steve Reich, Marcel Duchamp, Peter Greenaway, Go, chess, labyrinths, Pakistani Towers of Silence
