Is there an application that can take a bunch of small pictures and convert it to bigger (higher resolution) collage? Ideally it should be a native app that can run on a mac.

You could take pictures with any photo camera and then make a collage with Picasa.
I use Shape Collage, and have found it to be excellent. Works with Windows, macs and Linux :)
One of the screensavers shipped with Mac OS X (at least since Leopard) is able to do this with iPhoto Library contents. Impressive, but of little use in your case.
Imagemagick has a tool (montage) useful to perform such a collage. And yes, there is a mac version too.
A simple sample of montage and a more exhaustive sample is on Imagemagick site.
Montage is a command-line tool, e.g.:
montage '*.jpg' -border 2x2 -background white -geometry -50-50 -tile x3 out.jpg
You can obtain nice effects simply by following the site examples:
