I would search a port curses approach. Just a few routines to receive data 
from erlang (the whole list of objects or maybe update) and display them. 
Curses will care of screen repainting and effcient updates.

If you want to prototype fast there is a ascii art screensaver made in Perl
you can try control it from erlang...

well your are not constrained to 2D :-)

YMMV..
