The Goa'uld (pic by Derwin Mak) helmet was made by molding foam and aluminum over a biking helmet. The neck/shoulder piece and belt buckle were made from a yoga mat and some thermal glue. The shin guards were made from air-cure foam. The chainmail is a sweater, painted gold. The hand device was made from a leather glove, and some LEDs. The jaffa stick was made from a shower curtain rod, foam, and a model of seaQuest with flashing LED electronics added.
