Devilmarkus created his first CPC demo called JavaCPC demo. It features music and a small animation of 59 compressed pictures. You can download it here and read more about its creation and the technique behind it in the CPCZone forums.
Arnaud STORQ released the second part of his PHAT demo for the Amstrad CPC Plus, called – surprise, surprise – PHAT 2 ;-). This time it is not written in C but in good old Z80 assembly language. You can download the demo from his homepage.
Hey, another Amstrad Plus demo (needs at least 128k RAM) is there and this time it shows that it is possible to write a demo with C (the Z88dk compiler was used to program this demo). You can download the demo from Cpcscene.com .
If you also want to program with C for the CPC you can read this programming guide.
Roudoudou released a new intro which shows a 3D rendered face lighted by one moving light. You can download it from Cpcscene.com.
