I would check out these 2 libraries:

Fadecandy by Micah Scott: https://github.com/scanlime/fadecandy

LX and P3LX by Mark Slee: https://github.com/heronarts/LX

They both provide good starting points to working with LEDs arranged in arbitrary 2D and 3D configurations.

You can also check out the code for 2 different LED art projects I've worked on, both built on top of LX.

Tabula - https://github.com/squaredproject/Tabula LED fins on the side of a building in Palo Alto, visualizing earthquake data. Construction starts later this year

2Squared - https://github.com/squaredproject/2squared 50-ft LED trees created in 2014 for Burning Man and Coachella
