ok etrd improvement or new element etrd that you can change the chanel like wifi but with plasma streams. and you can set it to hit all other etrd points or just one or two or three so on because when you want more than one etrd thing on the screen and you spark one it often keeps sparking and zapping. please dont say it has no uses please PLEASE.
ETRD channels - suggested, rejected. If you want to block two ETRD sparking then draw a straight line of INSL between them and erase all the INSL except one pixel. (it checks for INSL directly inbetween two ETRD and plasmas if there's none.
