with its thin lines not very suitable for very small-scaled versions
there's also the not-to-be-taken-too-serious version of this, that's rearranged to have the words "pkg" and "src" readable when "built" while keeping the layout...
The 2D and 3D readable version of paper model v2
I personally like the horizontal layout (above) better
(not finished, tinkering with the idea of using only filled shapes, no cutting/folding lines)
Can't really decide if I consider this an improvement or not... Looks a bit like keyboard keys now, especially "src", doesn't it?
v4 + v1 = v5
I think I found my personal favourite. Either way, I'm also running out of ideas with this concept... If anything, I could try to round the edges of the glue tabs a bit. After that, for me, the only thing left is some tweaking of the letters.
Here's the child-proof (no sharp edges) version :)
Comes in two flavours: with less (v6a) and more (v6c) rounding applied. (Which makes v6a my new favourite. ... No longer true. Go v6c, go! ... Nah, can't make up my mind...)
Update: I've changed the stronger rounded version to have the roundings of the glue tabs resemble the roundings of the squares (if you flip them over they'll fit in the sqares now...).
Update 20070730: There's a bug in the v6c images; not sure if I will fix them, they'll become obsolete with the next ones anyway.
20070917: There is now an official logo proposal. As for my attempts, I actually had done some more already a few weeks ago, but got busy with other things... To finally round things off here, I'll scrape together what's been lying around and post it below.
