Dual letter illusion

Create a dual letter illusion with Web App or Python script.

Download the ZIP file with the app executables and run the one for your operative system! (The executable file will open the Web App in  dedicated browser window)

Each letter block is shaped from two letters that can be viewed orthogonally (3D ambigram). This can be simply obtained by the intersection of 3D letters.

Standalone Program 

Read the instructions and download the released executable files for your operating system from the Release Page.

The standalone executables have a slow startup time, please be patient!

Printables doesn't allow to load executable files, so they are uploaded on Github.

Web App disclaimer

You can find the Web App link and info in the Github Readme file.

Streamlit Cloud is a free platform, but it has some limitations. The app often crashes due to the free tier limitations. It usually reboot after some hours. If you want to use the app without interruptions, download the standalone executables from the release page.

Customize

• Text
• Font size
• Font
• All Google fonts are included
• Export the STEP file for further modifications

There are cool dual-letter generators online, but I wanted to make a project:

• Free tool (some programs are paid)
• No installation is required (you can use the Web App)
• Fully implemented in Python
• Easy access to different fonts

The example file STOP_WORK is obtained with Lato BlackItalic.

Enjoy!
