 an very simple and dirty pixelflut client to draw images, written in bash.
 pixelfloot was built during the 37c3. in its actual state, its just a mess. I hope i will find time to put it in a more usable and readable format. 
 
-## image format
-
-you need an uncompress ppm image at first. it is not allowed to be larger then 200px.
-
-convert it like so: `convert lol.jpg -compress none -resize 200x200 lol.ppm`
-
-after you have converted it to ppm, you need to convert it to a "pixel-list". 
-do it with `./pixelfloot_bash.sh convertimg lol`
-
-Have a look to the example .pixlist files
-

 ## examples
 
-Display image: `./pixelfloot_bash.sh floot lol`
+Display image: `./pixelfloot_bash.sh floot images/lucky-cat.jpg`
 
 image random position: `./pixelfloot_bash.sh floot images/lucky-cat.jpg chaos`
+  wider "chaos-radio": `W=1000 H=600 ./pixelfloot_bash.sh floot images/lucky-cat.jpg chaos`
 
-image shake position: `SHUFMODE=shake ./pixelfloot_bash.sh floot images/lucky-cat.jpg shake`
+image shake position: `./pixelfloot_bash.sh floot images/lucky-cat.jpg shake`
+  set the position  : `W=420 H=420 ./pixelfloot_bash.sh floot images/lucky-cat.jpg shake`
 
 move image with your cursor (needs `xdotool`): `./pixelfloot_bash.sh floot images/lucky-cat.jpg cursor`
 
 Use a color as "alpha" (remove background): `ALPHACOLOR=FF00FF ./pixelfloot_bash.sh floot images/cursor.ppm cursor`
 
+increase No of cuncurrent connections: `FLOOTFORKS=8 ./pixelfloot_bash.sh floot images/lucky-cat.jpg`
 
+```shell
+$ ./pixelfloot_bash.sh help
+./pixelfloot_bash.sh [floot|convertimg] [FILENAME|fill] ([MODE])
+MODE: static (env $H and $W for position)
+      chaos (env $H and $W for position range)
+      shake (env $H and $W for position range)
+      cursor

+available env vars to configure:
+RESIZE(int), ALPHACOLOR(hex), FLOOTFORKS(int), H(int), W(int)
