This is an example of a dashboard that is simply putting some block content in the left and the right.
It's worth noting that a little theming on this example would (and maybe even will, when I feel like it) go a long way. But for the moment I'm using the basic dashboard theme.
LEFT:
print dashboard_get_block('recipe', 0);
print dashboard_get_block('aggregator', 'category-1');
print dashboard_get_block('delicious', 'delicious-2');
RIGHT:
print dashboard_get_block('aggregator', 'feed-1');
print dashboard_get_block('aggregator', 'feed-2');
print dashboard_get_block('image', 1);
