Smashing Magazine recently presented 50 free UI-and-web-design wireframing kits.
Here I present an excerpt, namely parts of the collection of iPhone & iPad templates and resource links that are really useful to create nice (low-fid) prototypes, advertisement pictures, fake-screenshots or whatever you would like:

User Experience & Interaction Design are two of the most important issues when facing the current use of our World Wide Web. Though, most scientists and developers forget, that the Semantic Web and therefore also the Internet-Data’s Understanding is strongly connected with UE.
Within my future thoughts and projects I will be approaching the Semantic Web from more of a Interaction-Design or respectively user-focussed perspective. So obviously there are many interesting viewpoints to be taken into account when dealin with this wide-ranging issue.
The first question I stated was what are the different ways to look at this topic; here is a short answer to it:
- Statistical perspective (what is the data?/how does the data look like?)
- Computer Science perspective (hot to implement data visualization and interaction possibilities?)
- HCI perspective (how do users interact with data?)
- Graphic Design perspective (how can data be appealing?)
- another perspective?
Notes:
To begin with, I would like to use this post to note down a very incomplete listof professionals, conferences, symposia and institutes (which I may update from time to time), that are besides the obwvious ones, dealing with this topic somehow:
Catchphrases, Quotes & other thoughts:
concept of … highly adaptable … up-scaling views …
“Students shall choose projects with high societal payoffs, researchers have to employ the updated science 2.0 strategies, developers have to focus on genuine user needs”
Eventually, one of our best hopes for the future is that a large and connected group of people can change the world!”
Concept: Let us think of what should be achieved by 2020 and do something about it!

I would like to inform you about Cocoaheads Graz: This is (next to Cocoaheads Vienna) an Austrian COCOA community which holds user group meetings on regular base. These events are open to all who are interested and would like to talk about programming and developing apps for Mac OS X & iPhone.
The first meeting was on 09.11.09 and is repeated monthly on the second monday every month (at 19:00 in SciencePark so far).
I would also like to use this post as a “reminder” of NSLog specific format specifiers, I am not able to remeber 
So here is the list:
| format |
specified |
%@ |
CocoaDev Object |
%d, %i |
signed int |
%u |
unsigned int |
%f |
float/double |
%x, %X |
hexadecimal int |
%o |
octal int |
%zu |
size_t |
%p |
pointer |
%e |
float/double (in scientific notation) |
%g |
float/double (as %f or %e, depending on value) |
%s |
C string (bytes) |
%S |
C string (unichar) |
%.*s |
Pascal string (requires two arguments, pass pstr[0] as the first, pstr+1 as the second) |
%c |
character |
%C |
unichar |
%lld |
long long |
%llu |
unsigned long long |
%Lf |

Last weekend – til tuesday – we have been to the Weissee Glacier World for skiing. We stayed at the Rudolfshut there, a former Alpenverein hut, which is now a very nice hotel with sauna, indoor swimming pool and much more. Because of the reason that there was not much snow, we couldnot vary a lot with the skitours there, but nevertheless it was a wodnerful time and I would like to share osme impressions:

If you do not know yet what is possible to dynamically visualize with JavaScript, habe a look at this nice online-demo-collection (Google Chrome optimized). For example, one demo is a Starfield simulation and the Google Gravity demo.

While I am working on many projects dealing with information visualization, I would like to share a good online ressource about this research topic: IBM’s online visualization research site “MANYEYES“.
Finding the right way to view your data is as much an art as a science. The visualizations provided on Many Eyes range from the ordinary to the experimental. We’re deliberately providing a wide array of possibilities since this is an experimental site—and expect to see more soon!
Their featured visualization types include: Network Diagrams, Word Clouds (also links to Wordle), Word Trees, Treemaps, but also the more standard ones as Bubble Charts, Piecharts and histograms, World Maps etc.
Reading through the information given to a specific visualization type (and component) you also find information about for which dataset is it best chosen. => Datasets, such as: unstructured text, proportions, hierarchical structures, continuous change, relationships etc.
Have fun trying some of them out!
