This year's Halloween spooky effect.

To run it on #TIC80 you can download a TIC file here:
github.com/creativenucl...
If you'd like to try it online, it's here:
tic80.com/play?cart=4439

You have my blessing to play it at your Halloween party / scare kids with it 😄

We got placed! 🥉
Happy with that. There were some other strong entries.
We had good tech in this one, but I think it's fair to say it was beaten on art design.
Lots of friendship on the podium and we all know that's the real prize! 😄

#ByteJamuary 7: Print - making text pop!

TIC-80's text has a very distinctive clunky look. Here are a few ways you can smooth it out...

#ByteJamuary 6: Fifty stories tall. Striding through the land...

MODULO!

Value wrapping in percentage clothing - It looks like % but loops your values. What's it good for? Plenty!

A couple of options for running time through your code.

#ByteJamuary 4: "Sin and Cos - Magic? No, Even Better: Trigonometry!"

The secret sauce already! These two give the smoothest, gentlest movements - organic and complex.
Absolute heroes.

#ByteJamuary 3: "Aliases - Keep it snappy"

Lua allows you to assign functions to variables and this trick will keep your maths code tidier!

#ByteJamuary 2: "Code Hygiene - Optimise for the right thing"

If you're #livecoding, you'll almost certainly fall into some hole or other.

Today's suggestions are about giving your future self a better chance to dig a way out 🙂

@pimoroni.com #Presto Calendar

- Parses .ICS URLs (e.g. Google Calendar)
- Month view
- Day view with events
- Settings panel: Light/dark mode

Anyone fancy it?

#ByteJamuary 1: "Primitives - Spicing up the basic shapes"

Your first #ByteJam will likely involve a lot of basic shapes and they can look... basic.

Here's a nudge to explore! 😄

An astonishingly good #MondayNightBytes #ByteJam - some incredible effects, and a great Christmas send-off for the community. One to rewatch when it hits @scenesat.com!

Mine riffed on classic Amiga demo "State of The Art", with a dancing tree and moiré circles in the background.

Some more movement on the @pimoroni.com Presto calendar sketch:
- Connects to WiFi and NTP Sync.
- Time in the bottom right.
- Screen dims after 30s - touch to wake.
- Basic PoC Google Calendar integration (the number on each day indicates the event count).

A peek behind this ☝️ curtain.
The effect looks like it's throwing a lot around, and it is - sort of - but the geometry isn't moving towards the camera as it appears.
Here I've unhidden the animating texture that gets mapped onto the rotating spokes.
