I wonder how many other cool-ass projects like this are going on that we have no idea about.

Or the pages that give tantalising hints about a project, but there doesn't seem to be a write-up anywhere.

I think those Flickr albums are the write-up for how to make a Fotoopa.

Lots.

It's a simultaneously awesome and saddening feeling. Awesome because you know that there are unexpected amazing things that are going to happen. Sad because a bunch of them might give up from lack of exposure, feedback, etc...

Yeah. From the hacker's point of view many such projects seem trivial, not worth bothering to talk about.

You really need a spotter to find out which of your projects are cool and which aren't.

Then again, after trying to post a dozen times and getting nothing, one would just stop trying most of the time, and would work for the attic, so to speak.
