A little bit of map fun today with elevation data - a kind of topographic map, with lower elevations filling up first - spot the Danube, the Alps and all sorts of other things (elevation data from @CopernicusEU)
a few stills from the topogiffic map above - I'm not an expert but that looks like the Great Hungarian Plain 
the data doesn't cover every European country but where it does you can see some interesting things, including parts of the Romanian border
I'll add a video file too - may look fuzzy on here, but useful for moving the slider back and forth if you feel the urge
related - Scotland and Finland have very similar high points (there was talk about Norway gifting Finland the highest bit of Halti (1,365m) but it didn't happen
