A new version of the Rosace is being developed, hopefully for an exhibition in September.

The upgrade is significant :

• 25 fps instead of 15
• 200 LED diameter (instead of 120)
• Faster, synchronous (2-wires) LED strips
• RPi 3B+ instead of Pi B (v1.2 from 4 years ago)
• Introducing the 3RGB (de)compression algorithms (see #3RGB image lossless compression format)
• simplified auxiliary circuits in FPGA
• Multi-threaded programming (yeah! 4 cores!)

So it's a significant evolution but not a revolution, yet...

Stay tuned !
