About danwills

G'day! Dan Wills 'ere! I'm a full-time Houdini VFX Pipeline TD and Teacher (at RSP). I contribute a bit to a software called 'Ready', that enables explorations into 'reaction-diffusion'-type (ie field-based) simulations. Separately to work I've explored 2d fractals quite a lot, and dabbled with fractals and RD and other stuff in GLSL shaders (in an on-phone shader app) more recently.

I'm on YouTube as 'danwills' and there's the ol' UltraIterator blog below, and a flickr, which is probably the best view for my fractal images at present.

I'm always keen to chat about anything! I would love to turn some of these things into apps or cool games or shaders, so many possibilities! Send me an email:

    I think that that might be an aspect of the reproductive fitness of the 'hive' (or meta-organism) of all humans, rather than the genes in any individual or population. I agree indi…

    I'm reminded of this section of a Douglas Adams quote: "Anything that, in happening, causes itself to happen again, happens again." I like how this is not even specific to life nor…

    I agree with your sentiment but myself I'm not convinced that either politics or corruption are actually (in reality) one-dimensional as you're suggesting, despite fairly widely re…

    I am partial to this speed-is-life sentiment, and it made me think of this beautiful and wonderfully poignant demoscene production by Farbrausch and Haujobb: "Time Index". It is ma…

    I think there's utility in structures/patterns that can self-heal when damaged, but my imagination initially goes to usage in games and unusual UI. I've played with reaction-diffus…

    Ah thanks for letting me know! I had not set it to public. It's public now though! Glad you enjoyed it!

    Wow this is too much fun for simple sum-of-cosines but I shouldn't be surprised (have played with FFT a bit, and I know of Reimann Zeta Function.. sines are amazing!) I doubled the…

    Ah silly me, you put the sources in the comment!! Thanks for that I will have a read for sure! It struck me as looking a bit like a demoscene plasma effect but with a radial/angula…

    Thanks! Perfect match as far as I can see, nice one! How did you learn/know how to do this? The code was really interesting to read and tinker with! I made a version where the symm…

    Ah thanks for correcting me! Guess I glossed-over it earlier on in the article, apologies!

    Only partway through the article but it was a small shock when the word 'rodent' turned up unexpectedly: "...later, if the rodent reenters that place, the cell will fire" Totally f…

    Spot on! So much silly engineering would be needed to make this even slightly make sense for normal Linux 'users' and even then, if you can be root then there is no limit!? root ca…

    Ah wow that is awesome, thankyou for clarifying that! Today I learned there's another native fruit with a similar name, but you're right it's a totally different species! Good to k…

    Wow! I have not heard about that! A 40m tal! Quandong!? Crikey! Tallest I've seen is about 10m. I guess they usually don't get that big in SA. Must have been ideal conditions for i…

    I agree eucalypts are unusual, I also find them beautiful, especially ones with smooth light bark like Ghost Gum and Citriodora, which has light pinky-orange bark! Such a presence!…

    When there's physical access to the device it's nearly impossible to make any system unhackable I think, at least with current tech. In this case it's a deliberately injected (twic…

    Having played a bit with Discrete FFT (with FFTW on 2D images in a Shake plugin we made at work ages ago) makes the DCT coefficients make so much more sense! I really wonder whethe…

    I just put on a Venetian Snares album (Rossz Csillag Alatt Született) and thought I'd come back here to say the same as you have! I'd also add: It's like Aaron's whole career is sl…

    This worked in Opera on my (Android) phone, but on both Firefox and Chrome on Linux it seemed to not animate the rotation, and the rotation slider didn't seem to do anything either…

    Very cool! Reminds me a bit of some formulas that are available in UltraFractal (and Visions of Chaos by the looks) called 'ducky' or 'ducks' fractals, here's a blogpost about them…

    Thanks heaps! I very much love the 'old-school' jungle/uk-hardcore sound and didn't know about these more recent Suburban Base releases, and your other reccs were also great too! A…

    The ratio of computer minutes per programmer-minute has indeed gone to an amazing number nowadays! I work in VFX (at RSP) and this fact is vividly illustrated for me all the time b…

    Agree, but can't we just include both average _and_ mean? And maybe min/max while we're at it? Seems like that could give a much clearer picture (without even needing a graph!?)

    I totally loved the plasma effect from whenever I first saw it, and implementing it myself in Pascal/DOS was one of the first times I really started to understand a 'shading'-like …
