The Silicon Dawn Tarot is a new deck designed by Egypt Urnash (shatterstripes). It is not yet published, although a limited number of hand-made decks are available.
Please be aware that discussion on this community may be used as source material for the deck's book.
A list of links to the card images (for easy reference when discussing them) can be found here.
The minor and Court cards are based primarily on the Golden Dawn and the Crowley/Harris Thoth decks, while the Major Arcana are in a more traditional vein. The Golden Dawn's Book T is very useful as a place to start, as is Crowley's book on his deck. Be aware that many aspects of Wands and Pentacles have been swapped for this deck.
