I believe the answer is:

eisteddfod

I'm a little stuck... Click here to teach me more about this clue!

'arts festival' is the definition.
(I've seen this before)

'see it anew following round in 3d?' is the wordplay.
'anew' is an anagram indicator.
'following round in' becomes 'ddfo' (I can't explain this - if you can you should give a lot more credence to this answer).
'see'+'it'='seeit'
'seeit' is an anagram of 'eiste'.
'eiste'+'ddfo'+'d'='EISTEDDFOD'

Can you help me to learn more?

(Other definitions for eisteddfod that I've seen before include "Welsh art festival" , "arts competition" , "Welsh cultural festival" , "Welsh festival of music and poetry" , "Welsh arts festival" .)
