This one took a whole lot of time, almost solely because of the intersections of the red and blue beams. In addition the details became a bit small because I run with fixed line widths over all my figures. I do not plan to change this, but I do wonder sometimes.

In addition to the two beams that repeatedly pass over and under each other being perfectly horizontal, they also connect vertically at each end, and if you travel around the figure you will notice that you will either go only up or only down at the ends.

I am still keeping up with creating two a month. It is as tight as it can get now though, as can be noted I created this one the day before the last one was posted, so my margins are still shrinking.

Something to take note of in this figure is the pixelated diagonal line that crosses the figure. It actually scales as if all the steps had been at the same horizontal level. It is not impossible geometry, but the relationship is still not what you would expect.

The horizontal beams bend at one end, but not the other, while they are still connected vertically. This makes it possible to travel a horizontal distance that you can avoid by just climbing one side.

I was putting this one off as I could not imagine how to start with it, but then a friend commented on the sketch, that she liked the look of it, so I got the motivation to try my hand at it. Actually it turned out the process was quite straight forward, at least with the skill set and methods I have developed.

This is also when I decided I would add a Fillwork version next to the Linework link. Linework is the same as before, only the main geometry lines, while Fillwork is everything but the lines! Check it out! Some figures surely look nice without the lines, but as can be seen in this one some surfaces melt together when the lines are missing, which is why I keep the lines for the main image I post.

The four levels form a flight of steps, but if you take a closer look, you notice that the platform in the back is also connected directly to the platform at the very front, same with the second to furthest away platform.

This is one of the impossible figures that I myself feel works a bit better as just linework. This might be because the figure looks bent with the gradients, so the lines only version looks more clean, which is without saying really. Still, colors give volume and makes things look nice.

Both the tower and the wings transform from one end to the other. What was in front goes behind, what was a solid turns into air, surfaces from different structures melt into a new single one.

To get things ready for print services I have spent the last few weeks revising my impossible figure templates, scripts, and actions. This to convert them and all future art from CMYK to RGB and the aspect ratio to 4:3. While at it I adjusted the signature, background, website url, line colors and weights, added copyright text (tiny!) and made some actual updates to a few pieces. The process took more time than I had planned since I kept coming up with more changes I wanted to make, forcing me to go back and change files over and over again!

Another difference from before is that I will post images in the PNG format, a lossless format which generates reasonably small file sizes, this because PNG rocks, and compression artifacts don’t. I have finally managed to update all old posts to reflect this change.

I mentioned that I had updated some of the figures themselves, I will list which ones that has had the biggest updates:

• Tribar7
• Tribar6
• Tribar5
• Pillars

I ended up really happy with Tribar 5 and 7!

Oh, and as of today it is exactly two years since I finished the first impossible figure in this collection!
