A small Oslo company, and one app.

The entry, as it stands

An aksjeselskap is the ordinary Norwegian limited form: liability stops at the company, the share capital is paid in before trading, and the accounts are filed each year whether anything happened or not. Nothing exotic, and nothing here that a reader has to take on trust — every line above is a matter of public record.

One person reads the post and writes the code

Light Pear is small enough that there is no handover between the person who answers an email and the person who changes the thing the email was about. That is the whole operating model, and it is the reason this page makes no claims about capacity, teams or partners.

The work is Android: design a small game, build it, test it, put it on Google Play, then keep it working as the platform moves underneath it. Nothing is commissioned out. There is no agency arrangement behind the company and no second line of business waiting in the wings.

We also have an app on the store. It is described at the foot of this page rather than the top, because a company is not its newest release.

Most of a frozen rink can never hold a stone

Here is a fact about frictionless ice that we checked rather than assumed, because it runs against intuition. Put a stone on an empty square rink walled all the way round. Push it, and it travels until a wall stops it. The question is not where it goes — it is where it can ever come to rest.

Scroll on, and the rink below grows from four cells a side to sixteen. Watch the two numbers separate.

The rule behind it is one line. A stone only halts against something, so a cell can hold it only if a wall or a rock sits directly alongside. On a bare rink the only things that qualify are the border cells — exactly 4n − 4 of them — and everything inside is a square of side n − 2 that no stone can ever stop on: (n − 2)² cells of pure transit. At sixteen a side, that is 196 cells out of 256 the stone may cross a thousand times and never once occupy.

We checked it by brute force rather than by algebra: for every rink from 3 to 16 a side, every starting cell was pushed in all four directions and the landing cells collected. The simulated count matched 4n − 4 every time, and the gap matched (n − 2)² every time.

Where to write

Company matters go to post@lightpear.online. Anything about the app — a bug, a board that seems wrong, a question about data — goes to is@lightpear.online. Both reach the same desk; the split just keeps the two kinds of post apart.

Norwegian and English are equally fine. There is no ticket system, no form and no automatic acknowledgement, so if a reply has not arrived within a couple of working days, assume the message went astray and send it again.

Glattis

A winter puzzle on sheet ice. A carved stone glides without friction: swipe and it shoots off, sliding until a wall, a rock or a snow-bank stops it. Reaching the goal and collecting every crystal means reading the whole board first and planning where each slide will end.

Every level is checked by a solver, so a clean solution always exists, with a recorded best slide count to beat. It runs fully offline, keeps no account and carries no advertising — which is also why its privacy policy is as short as it is.
