Generate simple planets with Planetoids tool


Hooray! I’ve been keeping an eye on Tom Betts’ Twitter account to see whether Planetoids [ page] – his planet generation tool – would make it onto the internet instead of just providing lovely screenshots. It has! All praise ProcJam for giving me things to play with.


It’s a tool rather than a game and some of the shapes it spits out are more pleasing than others, but I like using the random button and just seeing what turns up. Some of the planetoids look like microscope visions of viruses but without the symmetry some of those offer, while others do look more like an object a space telescope could pick up.

It’s small but charming. Here are some of Tom’s creations:


[Disclosure: Tom works with Jim “formerly of this parish but we’ve forgotten what he looks like and almost managed to clear all his stuff out of the treehouse fridge except for that thing which used to be salsa but now growls and enjoys Sudoku” Rossignol developing games as part of Big Robot as well as creating his own projects.]

    God I hate Tom Betts. Making the rest of us look like idiots.

    Neat! I’m going to be spending a lot of time today hitting the “random” button, I can tell.

    Is this also the right thread to recommend other stuff from the ProcJam? Because ClĂ©ment Duquesne’s Accurate Coastlines is the fractal zoomer I was always imagining when I used to play with fractal zoomers. Spend a few minutes zooming in and then suddenly, quickly zoom all the way back out to BLOW. YOUR. MIND.

      Feel free – although I’m going to try to work my way through as many as possible over the next few days :) Might go for a roundup post if it gets out of hand so if that happens you can link there too
