How do some Kickstarter campaigns get panoramic pictures

I have the same problem and unfortunately advanced search/filters seems not available at the moment. It could be a good idea contact them and ask to implement such features, especially now that Kickstarter seems to grown a lot in popularity after Double Fine Adventure success and have a lot of new projects.

Anyway, back to your question, the only unfiltered lists I found were the Recently Launched and the Ending Soon lists. You can scroll them and find interesting projects you want to found.

You can track all new "Open Software" projects here:

There's no RSS option but you could can get the results emailed Daily or Weekly. Although if you want them Weekly I suggest using this list instead (since it shows all new projects over 7 days instead of 4 days in the browse list)

Hope that helps

Update

You can now subscribe to an RSS feed of all the results
