In this part of our series about transforming imperative Processing code into functional Clojure code we are deconstructing a ‘real’ loop for the first time. The code to be discussed is taken from Matt Pearson’s book ‘Generative Art‘, and we are using Quil for accessing the power of Processing in…
For my Clojure developments I’m using Emacs 24.4 (running on a Mac) with a cider 0.9.0snapshot, Clojure 1.6.0 and nREPL 0.2.7. Actually. When I’m starting emacs in my home directory and open a repl with M-x cider-jack-in, then I’m getting this warning: WARNING: CIDER requires nREPL 0.2.7 (or newer) to…
Part 1 one this series introduced Clojure programming beyond simple one-liners and expressions. We were setting up our environment and had a simple demonstration that illustrated the basics. We are using Quil, an implementation of Processing for Clojure, which is a great example of application of program flow that we…
When you start learning languages like Lisp or Clojure, you are plunging into the world of functional programming. Functional programming, as Wikipedia explains, is closely linked to declarative programming, and this means the direct opposite of imperative programming (which includes popular languages like Fortran, Basic, C and its derivatives, Java,…
St Kunibert, western transept
Much more interesting – and difficult – than just depicting the architectural truth in a photo is depicting the mood and meaning of this architecture. What is happening between these walls? What did this building mean to their builders and what does it mean to us today? How can I capture its spirit? Without producing kitsch? This is something I’m going to explore this year.

St Kunibert, Interior
I’ve visited this church almost six years ago, so a revisit was overdue. Kunibert, consecrated in 1247, is Cologne’s youngest and largest Romanesque church. I realized a few things on this bright Friday afternoon: your look on things changes over time; your technique changes (means: it’s getting better); my goals changed over time. The look is getting more careful, and despite spending for more than an hour, I’ve taken only a few dozen shots. Restricting yourself to taking less photos makes you more attentive; and the better your shots, the less post-processing you have to do. Continue reading
