ASCIIpOrtal: Soooon...
As mentioned on the podcast (what you don't know about that podcast is Kieron and I fought to the death afterwards. He killed me. These are in fact the words of Kieron wearing Alec's skin as a hat), we're not entirely sure why we haven't mentioned the surprisingly elaborate ASCII re/demake of Portal on the site as yet. Let's correct that. Did you know there's an ASCII re/demake of Portal in the works? And that it's surprisingly elaborate?
Specifically, check out its portal-view effect. It may only be symbols and coloured blocks, but it's as thrillingly disorientating as Portal-proper's space/time rift effect. Imagine playing this on your BBC Micro...
Sure, there's a part of me that wishes creator Cymon was spending his evident talent on creating his own, brand-new games rather than yet another tribute to a two-year-old zeitgeist, but it does very much seem as though he's going some place all of his own with it. His clear enthusiasm in this video is hugely infectious, too.
