You can have some fun with this type of compass. If you use it on a desk with a large metal support underneath it is difficult to get it work properly. Great fun for watching others debug. Try putting it next to a laptop/PC with the hard disk running. It just goes mad!

Love this one. I recently used a similar compass in a library maker day class. I only did 4 directions to get them started. I think they liked the blinking heart one better though. Either way they want more Microbit days so its a win...

A nice simple project, quick to implement, and something visual that changes according to what you do... a great little demonstrator for kids. With room, as you said, for refinements and imagination in terms of what to do with the display. I like it, from the point of view of STEM.

I don't know much about programming BBC micro:bit and how this compass tile is implemented, but i think your program has the following flaw:

pie slice corresponding to the north direction has only 45 degrees total (from 0 to 45 degrees), whereas pie slice corresponding to the west direction has 135 degrees total (from 225 to 360 degrees). Here is what i mean:

I think you should change last else statment to else-if to define west direction only in the range from 225 deg to 315 deg and add another else to show string "N" as range from 315 to 360 degrees should correspond to the north too. Like this:
