Nice project (especially since it uses STM8 eForth :-) ).
A practical hint: you're using a PE or PP enclosure which is transparent to UV, and that might cause damage to the eyes.
It might be advisable to use some kind of paint/paper/whatever that either blocks UV or transforms it to a longer wavelength (some fluorescent stuff might look cool).
