set patterns in blink(1)

I bought a blink(1) http://blink1.thingm.com/ and am playing with it. Does anyone have one of these? I'm trying to figure out how to set and play patterns. There is NO documentation and I can find no examples by surfing. The "help" gives the syntax as:

  --setpattline <pos>         Write pattern RGB val at pos (--rgb/hsb to set)
  --getpattline <pos>         Read pattern RGB value at pos
  --savepattern               Save color pattern to flash (mk2)
  --play <1/0,pos>            Start playing color sequence (at pos)
  --play <1/0,start,end,cnt>  Playing color sequence sub-loop (mk2)

I've tried a bunch of things, but nothing works. No idea what <pos> means, no idea what start, end, cnt, or for that matter 1/0 mean.

Any idea how to make it blink forever without the blink1-tool having to run forever (I was hoping maybe the --play would do that)

Any idea how to use --servertickle? `blink1-tool --servertickle 1` turns on apparently random leds  forever, but trying args e.g. 1,0,1 doesn't seem to have any effect. If I could get this to alternate color/off I could do my blinking light thing.

I'm running this on Linux using the command line tool: blink1-tool. If anyone has one of these nifty little devices I'd like some help. Thanks
