Contest is over
The
vote has given
Hades as winner with 10 points, for its terrific code showing a raytraced scene, beyond MrVain (7 points), with a nice oldschool-style demo, and RocketRider and its PureStrudel (5 points), on a total of 35 points.
This contest has been a real success, showing increased level, and great skills from a lot of people. I think not have been the only one to be really amazed by some entries.
Thanks to all competitors!
Will it be possible to do better for the
next contest?

Here it is the second
PurePunch Contest!
The rules have changed :
- 1° The program will be created using Purebasic 4.30.
2° The program source will only have 10 lines of 80 characters max per line
3° You only have one month to create a good utility, or FX, or whatever you want!
At the end of this period (July, the 1st), a poll will be created to vote for the best code. Do your best and it'll be yours!
Post the code in this forum, after adding and completing the following header:

I've had some trouble to count too, but those are max. 80 characters.

Woo, the level is high!

I've updated my version to use 79 visible characters, in case an end of line character counts too.
Also there is 16x16 supersampling now to get rid of all that unused space.
