Mix 1/2 of the sour cream, cream cheese, salsa, and taco seasoning
Spread into a round casserole dish
spread enough guacamole over the center taco dip to cover about 3/4 of it
Spoon the rest of the sour cream into a baggie and snip a corner for piping
pipe a dot of sour cream into the center of the guacamole, and make 3 rings around it going all the way to the edge of the guacamole
use a knife to pull from the center dot of sour cream to the edges of the dip - into about 6 sections (just as if you were slicing a pie)
cover and refrigerate until ready to serve
