Learning to see

A wonderful video on a variety of things, including learning and teaching to see. Make sure to check out Edward Tufte’s website if you love such things. I learned a lot from his books (and I am still saving to attend a seminar).

Free wallpaper: Failure is not an option

I was looking for the origin of the quote “Failure is not an option.”. You find some interesting sources. I still do not know if the source I found is the right one.

I really love the spirit in this quote. And the fact that the origin lies within someone from the Apollo 13 project makes it even more interesting.

Watching Luther on video and playing around with Inkscape and Gimp. This is what came out…

Cows dive!

All of you who have been to Miniaturwunderland in Hamburg know the little details. One of my favorites was mashed up into a wallpaper. I even created a diver icon for the cows!

Hamburg Binnenalster at night

Hamburg Binnenalster at night

If you hear Hamburg you can think of many things: You think of musicals, water, Reeperbahn, St. Pauli, Kiez, Elbe, Alster, Sternschanze, Altona and many more. I especially fell in love with all the reflections and lights. The following picture is made of 4 straight out of camera snapshots, stitched, cropped and finally I added a frame. Enjoy and add Hamburg to your vacation list.


A Wedding and a game

It was raining cats and dogs. Other people might consider this bad weather for a wedding or for being outside. But fortunately two lovely people said Yes to each other yesterday, at least officially because they must have said it to each other a long time ago. And yesterday evening I sat with the usual suspects and we had fun at the wedding. And we had something in common with the happy couple.

Stencil Munzee

You might wonder what the QR-code in the teaser image meant. That’s how we met.

Altough QR codes (kind of two dimensional bar codes) are heavily used in advertisment these days, they are also used as part of a game. And the name of the game is Munzee. Munzee is a GPS game (if you know geocaching the concept is not new to you) where you hunt QR codes in the wild. You get points by capturing (meaning: scanning) them actively or even passive (when your codes are scanned).

First you have to find these Munzees. They are mostly stickers which were hidden and you cannot believe how something can hide in plain sight until you tried to find some. Finding and capturing means collecting points and by collecting points you level up and…      …you will meet some people.

Apparently I even met two people who were brave enough to take the step into marriage. So what do you bring to a wedding if you are a bunch of people who are into the same game? Yes: game stuff.

You already saw the QR stencil. Usually these gamepieces are as big as approximately 4-6 keys from your keyboard. Looked like a lot of work to cut out the stencil…  With the support of it was possible to get a special icon for the happy couple and with some crafty hands this icon was turned into a greeting card. When opened it looks like a heart. The signatures were QR codes themselves. And there was even a Munzee puzzle!

The following pictures contain artwork and bodyparts of Karin, Bernhard, Barbara, Ina, Trixi, Florian, Gerhard, Monika and me. And you cannot see him, but there was the moral support of Emil.

These soft toothbrushes look a little bit rough in detail. From the distance things always look different.

Have a look at this picture and then think again which one of these you to use on your optical hardware: Glasses, lenses, microscopes, … A tissue might be soft for your nose, but not for high precision glass with optical coating…
