2d	awarded	Good Answer
May 15	comment	Styling every node without affecting coordinate styles The `above` and `below` keys (and all the others) not only set the anchor, but when a length is given use the basic layer transformations `\pgftransformxshift` and `\pgftransformyshift`, so effects will be additive. Thus, `above=2ex,above=1ex` result in `\pgftransformyshift{2ex}` followed by `\pgftransformyshift{1ex}`. The transformations are applied just before the node is typeset.

May 14	comment	How to project text onto a plane? @Toscho that seems like a much better idea. I've updated my answer.

May 13	revised	Draw polarized light Completely changed/simplified all "light wave" code.
May 13	comment	Is this a bug in pgf ? pgfpatharcto Path commands outside of a `pgfpicture` have no guaranteed behaviour. As p563 of the PGF 2.10 manual suggests: "Give graphic commands only inside {pgfpicture} environments". The spaces shouldn't really be there, but either way: `\nullfont` is used inside a `pgfpicture` to try and make sure spaces don't upset positioning.

May 13	comment	How do I generate in LaTeX a list of random questions avoiding repetitions? Hmm, it works fine on my PGF 2.10 CVS version. Perhaps an older version doesn't load the `pgfkeys` package automatically. Try putting `\usepackage{pgfkeys,pgfmath,pgffor}` in the preamble.

May 11	comment	How to find intersections between line and rectangle with rounded corners I can confirm this is a bug. The intersections library should apply `\pgfprocessround` for both intersection paths. In fact, it does it for neither. I'm surprised this hasn't been noticed before, in particular by the author of `pgflibraryintersections.code.tex`. `

May 7	revised	Drawing iterations of a recursive structure in TikZ / using node names defined in a loop Edited to make code result in picture more like OPs requirements
May 7	comment	Drawing iterations of a recursive structure in TikZ / using node names defined in a loop The `every hilbert node` style is applied to every node with numbers, to change the font use the `font` key, to stop the border being drawn, comment out the `draw` key. You may or may not want to stop the node being enlarged to some minimum size, in which case comment out (or change) the `minimum size` key.

May 6	comment	Drawing a 3D cone @wererabit I've had a go at getting the dashed line cone edges. Not convinced it's robust though.
