He briefly ponders why you would want a bathroom with a curtain instead of a door (ventilation?) then decides this is a problem for Tomorrow Bruce and goes to bed. He's kind of expecting to lie awake for a while worrying, but instead he passes out immediately and doesn't wake up until the sun rises or someone knocks on his door.

No one bothers knocking on his door! 

There are blackout curtains for the windows, but Bruce didn't close them before going to sleep, and as the sun rises, light seeps into the room through the ordinary curtains. Birds twittering outside the window are just barely audible across the double-paned glass, and if anyone else in the household is awake, it's impossible to tell through all the soundproofing. 

In that case he will figure out the shower controls, discover to his quiet delight that the spare clothes have printed labels rather than itchy tags, and head downstairs to see if anyone else is awake and can help him get set up with a tablet.

Cassea is making breakfast, singing to herself. 

And Elix is at the dining table, doing something on a tablet that might be homework or might be a game of some kind, hard to tell. 

"Bruce! Did you sleep well?" 

"I did, thanks! When one of you has the time, I heard there was a spare computer I could use to look up stuff like when my doctor's appointment is?"

"Oh, right, yes! I'm so sorry, I should have thought of that. Guess we don't exactly have a standard checklist for people arriving from another world! Elix, sweet, can you go get your Dad's spare tablet from the storage area?" 

"Moo-om. Do I have to. I'm practicing." 

"You can put it on pause, can't you? Which I can't do to these eggs." 

"I can go look for it if you don't mind me poking around in there. Or just wait until you're free."

"My son is perfectly available. Elix, you could show him your attic setup?" 

"I guess I could." Apparently this is appealing enough to compete with practicing. Elix pauses his tablet and hops up willingly enough. "Follow me?" 

"Sure. What were you practicing?"

"It's a new game for spatial skills! You need to fold or unfold things in your head in order to solve the puzzles in the maze and know what way your character should go, and it's on a timer, and -" 

Elix chatters about his spatial skills game, almost without pauses for breath, the entire way through bounding up three flights of stairs and swarming up a ladder to a trapdoor in the ceiling. "Here!" 

Sounds like a nifty game! "Ooh, a trapdoor, fun." Into the ceiling with him.

It's an unusually nice attic! It's finished, though not painted with anything more than plain grey primer; there's no exposed insulation-foam or boards or any other hazards for a small child, and it looks like it was probably set up as a playroom at some point. It's currently mostly stacked with boxes on one side. 

The other side has...some sort of complicated bizarre-looking contraption; it resembles a blend between a weightlifting rack, one of those electric massage chairs that show up at airports as a novelty, and an...ergonomic computer workstation? There are gloves hanging from wires, currently draped respectively over two halves of one of those ergonomic keyboards, and a number of other straps and Velcro bits, also dangling wires. All the wires snake together underneath the chairbench part, joining into a sort of umbilical cord that goes...somewhere...probably that box... 

Elix is bouncing with suppressed glee. "Dad and I made it!"

He bends and reaches, tenderly and lovingly, for a box resting at the foot of the chairthing, which, when opened, proves to contain what's recognizably a VR headset. 

"It's for working on the virtual-online Chaosworld! ...There's not very much there yet but it's a work in progress!" 

"Oh, wow, that's so cool! What senses and motor outputs does it support?" A virtual chaos world? Despite, or perhaps because of, his disinclination to all things chaos, he can see the potential and it's impressive. He can also see that he could easily spend the next several hours tinkering with the setup, but 1) it is not his, and 2) he has important life stuff to get done first.

Elix is delighted to explain! He flits around pointing out different wires-from-velcro-straps that do motion detection. The system detects movement in all four limbs and also turning your head! They're working on adding a stirrup-type setup and shoes, so that you can "walk" and feel appropriate pressure in your feet, and with more thought they might even be able to cover "different textures of ground to walk on." Currently the way to "walk" is to sort of fake the walking motion by moving your knees up and down, which has more verisimilitude than the previous version which was 'use the control on the joystick.' 

He surfaces after several minutes of talking nonstop. "- Oh right I'm supposed to get you a tablet one sec–" Elix darts across the room and dives into the stack of boxes in the other corner. 

Bruce has several ideas for getting different ground textures, the most promising one being loosely based on those Earth toys with all the pins where you can make an impression of your hand or your face or whatever, but yes, tablet, good idea. Time to see how differently general-purpose computer UIs turned out, which is also pretty exciting!

Elix digs out a fairly generic-looking tablet screen; it's about the size and thickness of a magazine, matte grey, with a flip-back cover like a book, and also a clear plastic roll-down cover that doesn't appear to impede using the touchscreen. 

"Okay let's go charge it!" He bounces back over to the ladder. 

Unfortunate how it doesn't fit in a typical pocket, especially when traversing a ladder, Bruce thinks as he follows Elix back down, though there's a lot to be said for nice big screens.

"Has this planet managed to agree on a single kind of charging adapter? Mine hasn't."

"For these, yes! Took five years of arguing about the standard before they picked one to roll out and imported this sort of tech from the Underworld. I think the Underworld still has about twenty different kinds of power-charging." 

"I guess it would, wouldn't it. Does a lot of stuff get, hm, beta-tested down under like that?"
