Abstract The Oberon Object Tiler extends the classic Oberon system’s philosophy of text‑ and command‑centric interaction to a visual, tiled object workspace. It treats every object – whether a document, module, or service – as a tile that can be laid out, snapped, and dynamically recomposed. This paper presents the design, implementation, and evaluation of the tiler as a lightweight, persistent object manager within the Oberon environment. 1. Introduction Oberon (Wirth & Gutknecht, 1992) combines an operating system, programming language, and GUI into a single persistent universe. Its original UI is based on mutable text viewers. The Oberon Object Tiler (OOT) reimagines this model: instead of text fragments, objects are first‑class tiles. Each tile is a self‑contained Oberon object (record with attached procedures) that knows how to render itself, handle input, and communicate with peers. oberon object tiler
