This is a really fun project that uses a 100 LEDs (100 pixels!), and a few off the shelf IC's to produce waveforms via an audio source. You can also plug in a probe like in a traditional oscilloscope.
All you need to make your own is available via my Google Drive - link below, including gerber files, schematic, board etc.
I've also done a step by step guide which you can find on Instructables
