Parallax P2 intro, that is. Super cheesy and basic, I know. Would be 32k if not for the enormous MOD file
A good thing at the start. A P2 is powerfull enough to make full size demos on it.

Simple demo that shows the P2
1) exists
2) can do cool shit
Fun to see. Also thanks for the mention. ^^

The P2 will be a great platform to make demos on. The hardware is as unique and cool as the Amiga was when it was released. Chip Gracey is the Jay Miner of microcontrollers.I'm serious!

The Enigma music is not (my opinion) the best choice. Enigma is ENIGMA. Period.
The scroller could have a proper charset (white)? Would be more readable and distinguished.

Good plasma thou =).

P2 = Propeller 2 Multicore Microcontroller?
What is it exaclty? An independent Raspberry-like platform? Just a chip? ARM, x86 or other architecture?

Yes, P2 is the new chip from Parallax. Custom architecture with 8 cores. This uses 6 of them to run the plasma, 1 to run the audio and another to drive the display (can be set to VGA/DVI/Svideo/etc, but I only tested s-video and VGA). VBLANK time is used to update palette, text bitplane and music player. The plasma isn't optimized at all, just muscles 3 sines, one atan2 and one sqrt per pixel per frame using the pipelined CORDIC unit.

As I alluded to, Ahle had the idea to turn it into an intro and suggested the music, so do indeed to complain to him :)
@ Wuerfel_21
Thank you man for the answer. Is it in C/C++ or in pure ASM?

Nahhh, not complaining. You know, I did listen to the Enigma mod very often, hahaha ;). And Enigma demo was a memorable blast "back then".

Great you have a mod replayer-routine, so more stuff gonna come soon ^^.

As I wrote, cool plasma =).

It's Spin2 (weird custom bytecode language), but all the hot loops are in inline ASM. The DL link is the source code, so you can look at it yourself if you want.
I'm sorry about the Enigma tune. It kind of is a big no no. It is one the most well known and most liked tune in the history of the scene. And it was from one of those demos that made the scene really take of. I know... But hey... I couldn't help myself!

Interesting. Not too easy at first glance.

Respect dudes! Thumb is for you!=)
