"(...I still don't grasp Hygrid - Wurmholes? - heads, tails? - etc.) ;-)"
its fun, in a way, to hear this little thread about hygrid pop up, even if it is about how confusing it is.
lets not forget that hygrid used to be the sito:synergy project to play on, as gridcosm was just a twinkle in eds eye. and, in its day, it caused much confusion! granted, the growing/flowing playspace made for a little less, um, tense environment concerning the "blendy vs quilty" flamewar, but it still had its flare-ups.
hygrid is, of course, still alive (and even active!); and all are welcome to play. just imagine a little tiny "cross" version of gridcosm -- a center piece with NORTH SOUTH EAST and WEST pieces off of it. simple sounding, no? no!
and dont EVEN get me started on wurmhoels! no one can explain those. i have no idea how ed and i even managed to program those to "work" "right". whatever that means.
(maybe i will go do a 4-way wurmhoel, just to see if i CAN.)
