I work for Wolfram and oversee Wolfram Community. I am a physicist, Mathematica enthusiast and faculty member at Wolfram Science (NKS) Summer School. I am an author at the Wolfram Demonstration Project and sometimes write for Wolfram Blog. I enjoy creating applications and art with Mathematica, some can be found on my website. I also collecting Mathematica graphics at a Pinterest board and organized a video group Mathematica Render on Vimeo.

comment Tool to locate bloat in a notebook?
Top Menu: Cell >> Delete All output - saves a lot of space for notebooks with a lot of graphics.

comment Is it possible to generate a Hasse Diagram for a defined relation?
@JOwen Do you know why standard representation then is not directed? alturl.com/jribp

comment Artistic image vectorization
@YvesKlett The code should work with any image. Are you interested in the used image in particular? - I do not remember where I got that image.

comment Artistic image vectorization
@YvesKlett thank you! I am not sure I understand what do you mean by "image were imported via some URL" and what it got to do with Copy/Paste - could you please explain? All images on MSE have their URLs and are downloadable.

comment Artistic image vectorization
@faleichik Thanks! Yes it is possible "to take cell colors from the original color image". ListDensityPlot produces graphics based on Polygon all of which can be extracted and put together with RGBColor function that was mapped on original ImageData. It's a bit tedious though ;) And good tip on Join - I use it myself when speed counts. See this on details how to extract polygons: alturl.com/hcbdv

Use VertexCoordinates or GraphLayout to "move the vertices locations". Use Placed, Rotate and even `EdgeShapeFunction' to play with edge labels placement.

comment Mouse motion heat map - live visualization and analysis
@belisarius my code hangs your FE? Could you let me know your system specs? It works for me.

comment Mouse motion heat map - live visualization and analysis
+1 Nice idea. Though it does, as noticed by others, hangs Front End - not sure why. Thanks anyway - go go creative thinking ;-)

comment Creating diagrams for category theory
+1 I am glad you used Graph and not GraphPlot. BTW I do not think it is necessary, but if OP doesn't like edge crossing over label Placed is the way to deal with this: reference.wolfram.com/mathematica/ref/EdgeLabels.html#72169267

Option GraphLayout -> "SpringEmbedding" will make it "more square" ;-)

@Jens Yes indeed - I feel this can inspire a few ideas. Thanks!
