I'm new to Mac (OSX) since a few days and I tried Pixen, too. But my mouse control was very strange and the palette function is very counterintuitive. But a few minutes ago I tried DosBox for OsX and Grafx2b, works perfectly (in fullscreenmodus). Give it a try. It has no tile features (as far as i know), but the palette feature is quite cool (except that you can't use HSV color model).

Copy both Folders into 'Applications', then you run Dosbox and a 'Z:' prompt shows up. Press [ALT]+[RETURN] (Fullscreen) type 'mount c: /applications/', type 'c:', type 'cd gfx2b' (or whatever your gfx2b folder is called) and type 'gfx2'. When you quit gfx2b, the dos prompt shows back. type 'exit' to finish your adventure

As far as I know, subpixeling is something different, as this article explains:

This is the basic approach which is used by the new macs to make their fonts smoother (When you have a Mac, use [CTRL]+Scroll-Wheel, and see what happens). With this technique it is possible to adress the displays lightdots an a smaller level than the regular pixels.
What Crow showed is just AA, when I'm correct, cuz he uses the complete nearby Pixels and is not trying to adress the specific lightdots of the screen through pixel manually red/green/blue pixels at the end of the square. I think ptoing or baccaman showed this somwhere in this forum (can't find the thread right now)

I'm really interested in getting the old Paintbrush version of windows 3.11. First of nostalgia reasons (it's what I started of with pixeling) and because I remember, that it was possible to save the current palette and load it again later, but maybe it's necessery to install a old windows version and to copy the paintbrush?

I don't think that the postcount /-rank matters (at least not for me). I think it is more that they try to make one's name.

I think the most important part is the content of a message. If it is pure fan-boy-ism like 'OMFG, THIS ROXX' or the opposite 'BHAA, THIS SUKS' then of course one lines should be deleted. But even if there is a long message (a few hundred words) and the content is like the afore mentioned, then it should be deleted as well, wheather it took time to create the message.

The other way round: if a short message contains every aspect like a longer, but not that well phrased message, why should it be deleted? Maybe the emssage sounds a bit harsh, but if the content is the same (and it is possible to get it) why should this be a bad habit? My mother tongue is german and I haven't got many experience in talking english, thus my answers may be phrased more complicated then needed. Maybe a native speaker could formulate it in one sentence where others need a dozen?

Uhm.. I hope I didn't got anything wrong
