Calendar Views: Upcoming or Recent I'm currently using the default calendar views "Upcoming" block to display upcoming events on my homepage. However, because events are infrequent, its common for there to be no upcoming events. In which case, the block disappears and leaves a big blank spot in the home page. 

Is there way to show either the next four events OR the last four events? For example, if there is only one upcoming event, it would add the last three events to the list and display all four in ascending order.

Thanks!
FYI, here is how I solved it. Thanks Rock, for the step in the right direction!

Overview: Used a custom module that creates a block that displays one of two view displays.


Programmatically created a view (hook_views_api, hook_views_default_views) with two displays: one that shows upcoming events (ascending order, up to 4 items without a pager), and one that shows the last four events in the database (descending order, 4 items without a pager)
Programmatically created a block (hook_block_info) that displays (hook_block_view) one of the two view displays based on the number of results in the "Upcoming" display ( $results = views_get_view_result('view_id', 'display_id');). 
Created a custom template file (views-view-unformatted--view-id--display-id.tpl.php) for the second display, which reverses the order of results so that they are still displayed with earliest date first.
