I had heard about the open source browser Minimo, but they just recently released their first trial build.

You can download a sneak peak at this build here:
http://www.meer.net/~dougt/minimo_ce/MinimoCE_0.002.zip. Keep in mind,
it is basically the second build that I made that actually rendered a
page successfully. When you check it out, remember I told you: Lots of
work to do; Lots of work to do.

I’ll have to check that out when I get home. Stay tuned for an update.
