Hello and welcome to my page. My name is Daniel Lerch and this is a personal site mainly dedicated to steganography, the ancient art and science of hidden communication.

“Pleasure to me is wonder—the unexplored, the unexpected, the thing that is hidden and the changeless thing that lurks behind superficial mutability.”

H.P. Lovecraft
