• tkinter: For GUI (included with Python)

Files

• hello_world_rickroll.py - Main application file
• never_gonna_give_you_up.mid - MIDI file of the song
• rick_astley_8bit_dancing.gif - 8-bit animated dancing Rick Astley (auto-generated)

Customization

You can customize the app by:

• Replacing rick_astley_8bit_dancing.gif with your own animated 8-bit GIF
• Changing colors in the GUI code
• Modifying the dance animation frames
• Adjusting the 3-second skip timing for different MIDI files
• Adding more visual effects
• Using different audio formats (though MIDI gives that retro feel!)

Known Issues

• MIDI playback may not work on all systems due to pygame limitations
• MIDI position seeking may not work on some systems (gracefully falls back to playing from beginning)
• The auto-generated dancing Rick Astley GIF is simple 8-bit art (you can replace it with a better one)

Credits

• MIDI file sourced from BitMidi
• Built with Python, tkinter, pygame, and PIL
• Created as a fun coding exercise combining GUI programming with multimedia
