Alterego
Bold Monday · Pieter van Rosmalen · 2018

A pixel-grid display family by Pieter van Rosmalen, built from overlapping bitmap layers that can be individually coloured or animated to produce depth from a two-dimensional structure.
About
Originating in 2001 as a Photoshop experiment layering identical bitmap letters with varying transparency, Alterego was fully developed and released in 2018 with five weights and three Big display variants. The stroke pattern progresses from an open waffle grid in Thin to a dense closed square mesh in Bold, and because all styles share identical glyph widths, they are designed to be stacked, coloured independently or animated. Despite its experimental nature, the family carries a full Latin Extended character set with Vietnamese, Greek, Extended Cyrillic and Hebrew support.
Classification
Alterego is a pixel-derived modular display typeface built from overlapping bitmap layers; its criss-cross stroke structure and grid-based construction place it firmly in the modular/pixel display genre.
