Atari user customised GUI

As an addition to the earlier GUI interface analysis, I found this video by Paul Slocum demonstrating his customised interface for the Atari 2600:

The video may only be short, but the interface is even simpler than the ones previously analysed. It's the ultimate in simplicity - the icons are minimal and obvious. The cursor, which is actually only a block of colour, can be moved around using the directional keys. The 'exit' icon is reduced to a simple white pixel whilst the pop up window is outlined with a dashed line. Even the text (see 0:33) is rendered in pixels.

I wonder if something like this could be applied to Teletext? Taking the GUI back in time by mixing modern interfaces with a teletext aesthetic.
