is there any music similar to Boards of Canada?
 

because i haven't been able to find any. BoC has some amazing stuff, and i just wish they had more of it. [surrender]

Autechre, Four Tet and of course Chris Clark (cos he's a nice guy) or Clark as I believe he's called these days.

also try out aphex twins selective ambient works 1 and 2

bola is a must! soup is the best album, all his other stuff is mighty fine too.

there are a lot of artists on warp records with a similar feel, just go onto bleep.com and listen to parts of the warp records back catalog and skam records to see if you like anything there.

there is also christ, m83, nathan fake, plaid, two lone swordsmen, mira calix and as mentioned above clark who are all 'similar' though they all go there own way in their works.

You might want to check out Boom Bip as well, not quite the same but still sth worth listening to.

Here is a list of what I think the best IDM bands are at the moment

Proem
Lusine
Vector Lovers
Esem
Ochre
Tycho
Adam Johnson
Deru
Deadbeat
Arovane

Here is a fanmade video of a proem song off his new albulm. Proem may be more melodic than what you are looking for
