Everything about graphics...

Capabilities

Computers use pixel graphics, where the screen contains re-colorable tiles, this is quite mundane but its a improvement of this mods primary inspiration Computer Craft, which uses mainly a font render, and a adjustable palette of colors. also a improvement is how NEET uses 24 bit color for its main display with an alpha channel (transparency)

also of note are the 'physical' displays on the computer blocks, a small binary color (nothing or green) 3d renderer thats API controlable, and can be animated in real time to give computers a visual flare programmatically.

Built in graphic API

The main screen is linked to a powerful (if hacked together, sorry) API, containing lots of fun functions for bulk drawing data, flood fill tools, fun experimental functions for drawing bezier curves, circles, and every kind of octo/hexa/trio-hedren, and finally copy pasting / saving graphics via independent graphical 'layers' that can be copied from the screen or created independently

Additionally the ingame renders can make quite the impression of their own!
