3D Cellular Automata

I put together a new 4K resolution movie of some 3D Cellular Automata rules. All the parts were created in Visions of Chaos and rendered using the excellent Mitsuba renderer. The grids are up to 500x500x500 cells in size and the larger grids were over 25 million active cubes per frame.

I am always interested in new 3D CA rules, so if you do download Visions of Chaos and find any new rules let me know.

While I was browsing the archive section of Complex Systems I found some papers by Carter Bays here and here that discuss some “3D Game of Life” rules. Unfortunately they require special setups for the gliders to appear. I am more interested in finding rules that can lead to interesting behaviors from random starts (or from a smaller block of random cells). It is much more difficult (or at least it is for me) to find 3D CA rules that do not quickly die out or expand to fill the grid in a continuous random mess (and I have tried loads of random rules over the years).



A word version of ADDLED. ADDLED seemed to turn a lot of people off before they even tried it because of the maths involved. Google Play is full of word related puzzle games so maybe Gridwords will attract more players.

Words need to be found within grids of letters. Starts simple with common 3 letter words in small grids but the complexity of words, letters per word and grid size increases as the levels go up.

Gridwords is 100% ad free.

Quit Smoking Helper for Android

Yet another of my older Android apps I have updated and re-released to the Play Store.

Quit Smoking Helper gives you various stats to encourage the quit smoker to stay quit.

The screenshots show my current stats. The statistic that always amazed me is the time saved. That is time just inhaling and exhaling the smokes.

YOTZ is updated and back on the Play Store

Another one of my android apps I finally got around to updating and releasing on the Play Store.

YOTZ is my version of the well known Hasbro game Yahtzee. Only for 2 players at this stage because the more I think about trying to code a decent computer AI opponent the more my head hurts. There are some interesting research into Yahtzee strategies out there like this one so maybe one day I will have a go.

YOTZ allows you to play up to 6 games at once. Multiple games are much more interesting than just a single game at a time and lead to more strategies in play.

As with all my apps, this one is 100% free and 100% ad free. YOTZ also needs no permissions to run.

Freedom of knowledge and Sci-Hub

If you are a nerdy science type who likes to read academic and or research papers (for fun or for knowledge) you will have seen for a long time now that a lot of the papers get blocked behind a page that asks you to pay for access to the paper. These “paywalls” usually amount to around $30 to see one individual paper. If you are a university student you can get around this if your institution pays the publisher, but for your average person you do not have free access.

Science Paywall

This is very frustrating. Knowledge needs to be openly shared for the human race to advance. The power of shared knowlegde the Internet brings should not be restricted.

SCI-HUB is the latest completely awesome solution (note, may not be truly legal – see wikipedia article for the full history) that gets you access to these paywalled papers. Taken down for now, but mirrors will always crop up (including harder to kill TOR onion sites).

Newton Quote

I could go on for pages about the arguments out there. Do some googling on “academic paywalls” to read all the hatred against them. I gave up trying to find a page that said it thought paywalled knowledge was a good idea.

Ever since starting this blog I have always tried to only post positive topics. The old “if you don’t have anything good to say then don’t say anything at all” line. But this topic has and will continue to annoy me past the point of silent indignation.


ADDLED updated and re-released

After some updates for the latest Android versions I have now released the latest version of ADDLED to the Play Store. ADDLED is 100% free and ad free.

The aim is to find a set of numbers that add up to a total value. Initially the levels are simple with just sums using positive numbers, but later levels give larger grid sizes and negatives, multiplication and division.

As the difficulty increases there are more strategies to implement to get through levels.

The levels are quick enough to fill in a few minutes when you have some spare time. There are 5000 total levels to keep you more than occupied.

If you think this is your sort of puzzle game, download ADDLED through the Google Play Store.
