Getting into image manipulation, I created a few filters to change the look and feel of digital images. Though the software is not the most efficient, the results are looking good.

For demonstration purposes I used an image from my post Stacking Stones.

This filter I call Cixel, because it combines square pixels with round circles.

Again working with circles, the Draw filter tries to imitate a drawn picture. The Drawing filter applied

Using lines and a fixed point, thed Stretch filter stretches the image to the lower right corner.

Starting at the screen’s center, this program draws randomly long lines in a random direction. The lines cannot leave the screen.

Using the extended pygame graphics function pygame.gfxdraw^[1], this program creates randomly colored trippy circles. There are 𝟣𝟢𝟢 circles, which get redrawn every 𝟣𝟢𝟢 ticks (~ 𝟣.𝟨 seconds).

Stacking Stones

Driven by pure boredom, I started picking up some stones near a lake and tried to stack them on top of each other.^[1] I thought, they looked kind of cool — these are my favourite ones.

Random Resource Locator

I once heard that every domain containing three letters of the alphabet and ending with ‘.com’ was assigned to some web server. This would mean, all 𝟣𝟩𝟧𝟩𝟨^[1] domains were used.
To test it, I wrote this little Python program.

Jasteroids

This game is my interpretation of the all-time classic arcade game Asteroids. Although it plays a little differently, it has all the components of the original game. The rocks are stationary, but — if destroyed — split into two smaller pieces. You can either destroy the rocks via missles or by just flying right into them.

After having programmed Jic-Jac-Joe — where you need to connect three pieces —, I now programmed Connect Four (four pieces).
This version — although it does not have a computer player — includes win detection.

Caesar Cipher

This program lets you write a short line and encrypt it using Caesar’s Cipher. It shows the two prior and next rotations, as well as the current encryption key.
