Collision detection was usually turned off in these public spaces, so that if you bumped into someone elseâs tuxedo, you would pass right through it. Ranged all along the walls, floor, and ceiling were hyperjump nodes: the gates, or magic doors, that opened into the different cyberspace worlds accessible in one jump from the Bay Area Netport. The nodes were shaped like spheres, so that you could dive into a node from any direction.
Set here and there in the walls were square portals marked âREST ROOM.â These were places for meeting people and for tweaking your tuxedo. Gretchen flew into the closest rest room and looked into the mirror.
âGod, I look like you , Jerzy,â shouted Gretchen. âCanât you get me a female tux?â I did in fact have a tux patterned after Carol, but I didnât want Gretchen to wear it.
I leaned close to her headset so she could hear me. âMaybe later. Why donât you go ahead and stay in my tux for now? Thereâs still a lot to see.â
âAll right,â said Gretchen, drifting back out into the Netport. âWhich way to Magic Shell Mall? I read an article about Magic Shell Mall just last week.â
âItâs right over there on the wall to your left. The extra big node thatâs flashing pink and light blue?â
Just as Gretchen pointed her finger to fly into the cyberspace mall, my doorbell rang. Shit! Already quarter to four! It was one of the kids!
âGretchen, I gotta get the door. Donât worry. Iâll keep them out of here. Have fun.â
I threw on some clothes and left my bedroom, closing the door. Iâd say hi to the kids and come right back.
Tom was at the door, tall and full of beans. He had bracesâthe main reason Iâd quit teaching and moved to California was to get enough money to pay for the childrenâs braces and college. Tom had grown something like six inches in the last year, and now he was taller than me. He was wonderfully enthusiastic about life.
âHi, Da!â He poked me playfully in the side, right under my ribs. âLetâs play suckling pigs on Daddy!â
âStop it!â I cried, clamping my elbows against my side in self-defense. Tom kept poking, rotating his fist back and forth to achieve a grinding motion. âGet your hands off me, Tom, or Iâll beat you! Stop it!â I deepened my voice to sound more authoritative. Tom was whooping and laughing. I made fists, stuck out the knuckles of my middle fingers, and pushed against Tomâs hard-muscled stomach, trying to give as good as I got.
There was a squeal as wide-faced, grinning Ida entered the fray as well. âGet Da!â she hollered, and set her fists to rooting against my abdomen. Ida was always ready to join in wild fun.
I fell to the floor with the two kids on top of me. I rapped on Tomâs shin hard enough to give him pause, and managed to squirm free, though Ida still hung onto one foot. Tom was just about to start back in on me when Ida sat up, looking puzzled.
âWhoâs that screaming?â
It was Gretchen! I ran full tilt to the bedroom. Gretchen was clawing at the air, unsuccessfully trying to get the headset off. The desk monitor showed a voodoo blur of seething ants, and the skritchy ant sound percolated faintly out of the headsetâs earphones. The ants completely blocked the view through the screen; they moved about in the self-similar patterns of turbulenceâlike the smoke of an explosion, like the florets of a cauliflowerâthreeâdimensional patterns of fractal lace, dark patterns veined with thin dotted lines of color. There was no way to see in past the ants to wherever Gretchen had been when theyâd come.
Despite Gretchenâs terror, the ant patterns were so fascinating that I decided not to turn off the machine. I pulled the headset and gloves off Gretchen and helped her out of the chair and onto my rumpled bed. She was shaking
