Of all the years I’ve had, this has certainly been one of them!

This is a near-complete list of my publicly available creations, all built during lockdown.

I created something new every week since March, so I’m hoping these will bring some good memories to look back upon, and not just the list of everything I’ve lost.

Details of the talks I gave can be found on the Steven Goodwin speaker page.


In brief...

LEGO : 8 models and videos

Magic : 5 tricks and routines

The best way to sort LEGO

Full article
Conventional wisdom dictates that LEGO should be sorted according to their colours. After all, this is how the LEGO company sort their blocks on the pick-a-brick wall. But, I offer that it is the very worst way of organising them, and this blog page attempts describes a better method...

Magic

My last gig in 2020 was at the Magicians Showcase, one of my favourite venues. Not only did lockdown stop the event, but the theatre was also sold in the same month! So naturally, most of my magic has been either theoretical, or for online audiences. Neither has the buzz of a sell-out 220-seat theatre.

What items bend and twist, using only the power of my mind!

Ball and tube

The tube is only wide enough to allow one ball to pass. Yet two do.

A new take, on an old trick...

Summers Edge

An award-winning invention where the names of two freely-selected cards are found written on the deck itself. Secret!

Inspiration in Isolation

Hear it
I wrote an album of songs, with the intention of the lyrics never mentioning the words 'lockdown', 'isolation' or 'in these uncertain times'.

Symphony Number 1.1 in C# minor

Hear it
"Symphony Number 1.1" is an opportunity to use the same generative algorithms used by one of the pieces in the original symphony, Fractal, to generate your own music.

By applying the mathematics of a Golomb ruler I have generated this piece of algorithmic music. Listen to 'Golomb ruler - part 2' here

Windswept No. 3

Hear it
When Phyllis Wager travelled to East Greenland as part of a British expedition in 1935, it was so unusual for women to travel to the Polar regions that special permission was needed from the Foreign Office. What can her typewriter tell us about her work? Listen to 'Windswept No. 3' here

Software

EMF - Emulator Framework

Watch on YouTube
em.ulat.es site
EMF stands for the emulation framework, which aims to significantly lower the barrier to entry for emulation developers, and would-be emulation developers.
It exists in two parts: the first is the EMF builder which takes an XML description of a computer system, and translates it into source code, generating an emulator, assembler, and disassembler - all from the same originating file.

ZX Adventure

Buy it!
I spent a lot of time writing emulators this year, so I wondered if I still knew how to code for the machines I've been emulating...
So, I wrote a game for the Sinclair ZX81 in Z80 assembly
It was released in 2021

I tied the original 1K chess game to an emulator, and hooked it into the lichess.org API

Space Pointer

It lets you select a planet, and time of day, and the arrow will spin around to point to its position in the sky.

Spin Table

I've sometimes seen nice image previews that let you rotate your view camera around a particular object, giving you a real 3D feel, so I built a table that spins around so that you can make your own.

Chess Art

Here, by way of a distraction, is the Z80 assembly source code to ChesSkelet which builds down into just 377 bytes. (Yes, that's smaller than the infamous ZX81 1K chess program!)
I built a complete set of these!

Art

Vitruvius 2.0 - This is a piece I created for Cambridge Museums' "Woven Histories" exhibition. It's not the best work in the project - it is billed only as "The best of the rest" - but, as a failed artist, that's good enough for me!
