Tree in Turquoise

I recently had the pleasure of making another baby belly body painting. My dear pregnant friend is a little obsessed with turquoise and thus the belly is themed in that color. She chose a beautiful symbol of growth, a tree with strong roots and a wide crown. See the final picture here, following by the making of and some close-ups.

Horse

A while ago, I painted a dragon in the element of water on a baby belly as this mythical creature is the Chinese zodiac of the baby. By now, the little boy is getting a brother or sister and I had the opportunity to turn this into a little zodiac series. The “second one” will be of the Chinese zodiac “Horse” and the element “Wood”, thus we decided to paint a brown horse. See a time-lapse video of the making and some images of the final result below.

Reverse Geocaching Wedding Gift Box

A while ago, friends of mine got married. Like so often, we tried to come up with some extraordinary cool wedding present. They both enjoy hiking and geo-caching, which inspired us to make the following present. We found an awesome idea online, the reverse geo-caching puzzle. The original description can be found here: http://arduiniana.org/projects/the-reverse-geo-cache-puzzle/

The idea is to give a box to the couple. Inside the box there is a gift (whatever you like to give as a present.) The box itself is locked and has one button and a display. When the button is pressed, the box retrieves its geographical location via a GPS receiver and displays a distance to a checkpoint. The holder of the box has to bring the box to the checkpoint. When the checkpoint is reached, a new distance to another checkpoint is shown on button-press. After reaching a couple of checkpoints, the box opens when carried to the last checkpoint. The tricky thing is that only the distance to the points is shown and no other information like compass points etc. Therefore, the holder of the box has to press the button in different locations and derive the coordinates of the checkpoint from these relative information.

We re-implemented and customized this original idea to give it to our friends. This article describes the making-of, including some documentation of the actual puzzle-solving. This project was done by me and four friends of mine in a truely globally collaborative way. The contributors to the box were located in two different countries, three different cities. We created the box in two different geographical locations and doing collaborative coding and soldering sessions via video conferencing. Only shortly before the actual wedding ceremony, we came together for the final assembly (and some hectic last-minute fixing).
