He wrote short stories and screen plays, including two black and white silent movies.

[2] After World War I, Wallace built a small cabin in the forest near Carmel-by-the-Sea, California, which he used as a laboratory for experimenting with telepathy, which he sometimes referred to as "mental radio."

He wrote about messages from the dead, from ancient Greeks, ancient Egyptians, Vikings, and Atlanteans, to more recent dead, such as Thomas Jefferson and Charles Darwin, and transcribed messages from and drew pictures of extraterrestrial life, especially from the Pleiades star cluster.

[1] He showed newspaper readers what a good columnist and illustrator was like, made a lively war correspondent (Jap-Russo) became a hunter of big game, helped settle a colonization on a cocoanut Island off Mexico, thought he'd write some books of serious importance; he did; then decided to devote his life to science!

His works were recovered from his Carmel cabin after his death, and some of his art and diagrams were included in The End is Near!, Visions of Apocalypse, Millennium and Utopia, ISBN 0-9664272-7-0, published by Dilettante Press.
