What pen would the late Jacques Derrida endorse?
Maybe this one, from www.go-pen.com. The fountain pen has been around for a hundred years at least with little to no changes. Now, a group of smart people invented a biometric pen that works on any surface, doesn’t leave any marks but remembers your hand moves as you write, converts your handwriting into text and stores the information digitally. Like a Stylus pen but only portable and surface-neutral. Although I’ve always thought of Derrida’s arche-ecriture as a whimsical invention of a French philosopher, technology is capable of materializing his writing fantasies.
