microscopic sigils etched into ritually purified crystals to give them the ability to think, linked together with carefully designed patterns made of highly specific materials to other thinking crystals, with a panel of liquified crystal--or, in the case of the emerging μLED panels, millions of tiny crystal balls--used to present information to the mage operating it, and other crystals with different microscopic sigils that let them see instead, that the mage uses to tell the artifice what it should be doing, in conjunction with more of the carefully designed patterns that have deliberate gaps in them, gaps which the mage can close and open as another method of telling the construct what to do. These constructs can also link to ley lines that span the globe, allowing rapid communication with other like constructs--and large sigils made of miles of precisely positioned and sized copper wire can make additional, miniature ley lines through which the devices can both draw power and link to the main communication leylines. Sorcerers are currently experimenting with longer and longer range communication without the use of leylines, sending information through the aether using specialized arrangements of copper and purpose-made magic-infused stone that can transfer information, though not objects, between the physical world and the aetherous otherworld where information can move without leylines to be transferred back to the world of physicality using another identical magic-infused stone
