New pens

2016-03-06 09.29.40

Just bought a set of new pens, Rotring 2000 isograph, with several types of nibs. It means I can work faster with indian ink and have more control on the broadness of the lines I use in my work.  I normaly use the traditional nibs, since that works the best, but for design, these pens are very good indeed.  Teset days I worked on cleaning them and testing them. One of the papers used for that (see below) I lateron used as writing paper for a letter to De Villo Sloan in USA…….

On my new drawings you will see the results since they are used now in the new drawings I make on a weekly basis.

The OLD IUOMA website

For people doing research, please notice that the old IUOMA website is still available. I started the website in 1996 when the HTTP protocols first were used to make the WWW websites.  It grew from there and was completely typed by hand.

Because maintaining that old structure because too time consuming and also I didn’t wantbto throw away the old building, it is still there through:


Just try it…..  The new www.iuoma.org website is build around that old website because I use a trick. The old website was done with direct addressing, and the new website is done with relative addressing based on a new link to the root. This works out just fine leaving two websites alive where I can go from the old one to the new one without any problem.

Also historically it is interesting. The old website gives the feeling of how that old programming went. The new one is a blog with all the advantages given by WordPress in maintaining such a website.

For more historic information you should visit:


Ans look for the old URL address of the starting periode:


It brings you back in those old years of building websites and you can actually look back on the structure there were back in the 90-ies.

Check any of the old versions of the website, and see and read all that was published decades ago. Funny how the Wayback machine has captured all these old Geocities websites as a timemark for the new world to research

And remember, before the WWW-years I used the BBS-structures that made information available through the digital channels as well. Charles Francois (Belgium) documented the structure quite well:



Drawing A Drawing


In the series “Analog humans Digital Computers, I made a new drawing today that deals with the digital making of drawings. I work with the traditional indian ink and Peterburg water colours, and yet use a scanner to publish the drawings on Internet. Why not go digital all the way?

Well, I must confess I just lake paper, and working with that ink and paint. Also I like it that the indian ink leaces a structure on the paper and that it glances when the lighht shines on it. That vanishes when I scan it and place it on internet. Bits and Bytes are not the same as the analog stuff.

Multimedia in progress

In 2 months I will be doing two workshops for teachers that work at a college. I will sow them the ways to use a 3D pen and also let them think on how to use it with their students. For the occasion I will have access to lots of 3D pens, so it will be interesting to see how that goes.

For my art I am testing a few things. This afternoon I made some letters with the 3D pen that have become objects. I placed them on a scanner to make an color-copy of the letters. On that result I put again the original letters and took a digital photo of that on my working table. Next step is to put that image on some places online, like Facebook, IUOMA Network and some ‘pataphiscal platforms, and now also on this www.iuoma.org website.

So from idea to plastic to a color-copy into a digital photo and now going into that digital worlds. Multimedia for sure.

At the workshops I will probably let the teachers first make a letter of their choice to let them test the 3D pens and to see if they get the idea.  We will collect the letters and will try to make a word of it that guides them into the next assignment. It will be an interactive workshop for sure.

Maybe they should make a cup to to put the letters in:

‘Pataphysical research

2015-12-05 13.14.01 2015-12-05 13.14.22

When you want to know more about ‘Pataphysics, the first thing to do is research. Found a goog book after all the Internet documentations, and started to read. Yes, it is a useless guide if you want it to be. Just discovered a lot of links to what I do right from the start.
