Democratic Palette

palette-spots

Democratic Palette, 2016, Ethereum Contract and HTML/JavaScript/CSS.

A palette of twelve colours that anyone can set on the Ethereum blockchain. Every vote for every colour is tracked and the top twelve make up the palette.

palette-vote

palette-representations

palette-squares

palette-stripes

The images above show various different visual applications of the palette and the use of the GUI to vote for a colour (the GUI appears if you click in the window displaying the canvas).

Note that the above images are from test runs. The current palette on the live Ethereum blockchain looks like this, ready for people to vote on:

You can download the interface code here, it’s in the dapps/democratic-palette directory.

To use it you’ll need an Ethereum node running locally, and to vote for colours you’ll need some Ether.

“Hot Cold” on Homestead

Post author By Rhea Myers
Post date 2016-04-19

cold-hot-live

Here’s “Hot Cold” live on the Ethereum “Homestead” network.

“Hot Cold” calls back to Art & Language’s 1960s Conceptual Art involving abstract aesthetic properties. It looks (and is implemented to be) twice as complex as “Is Art“, but it’s still really only one bit of information.

You can run the user interface locally in a web browser with an Ethereum node such as geth. Once geth is running, the user interface can get the contract’s state from the blochchain and, if you have Ether for gas, modify it. If someone else changes the contract’s state, you’ll see this updated.

If you want to change the contract’s status without using the user interface, you can do so using the contract’s address and ABI in EtherWallet.

The address:

0x53cd5d6bebff1eef892c191875e4d963875f50d7

The ABI:

[{"constant":true,"inputs":[],"name":"cold","outputs":[{"name":"","type
":"bytes4"}],"type":"function"},{"constant":false,"inputs":[],"name":"swap","out
puts":[],"type":"function"},{"constant":true,"inputs":[],"name":"hot","outputs":
[{"name":"","type":"bytes4"}],"type":"function"},{"inputs":[],"type":"constructo
r"},{"anonymous":false,"inputs":[{"indexed":false,"name":"hot","type":"bytes4"},

“Is Art” On Homestead

Post author By Rhea Myers
Post date 2016-03-28

is1

Ethereum has been live for several months now and has progressed to the point where the network has been declared stable.

So I’m deploying my contract artworks to the Ethereum blockchain. First up is “Is Art“.

“Is Art” is an Ethereum contract that can be instructed to nominate itself as art (or not). Whoever toggles the contract’s state as art sets it unimpeded until the next person sends a transaction to change it. A more rational system should be used – bidding, voting, a prediction market. The Duchampian aesthetic transubstantiation of artistic nomination is long played out. It is an art historical found object, as basic as a contract with a single bit of state. Brought together, the art historical and the contemporarily technological (or their audiences) can mutually animate and interrogate each other.

If you want to change the contract’s status without using the user interface, you can do so using the contract’s address and ABI in EtherWallet.

The address:

0xa95301a50551dfe16e180dec3fe0044e94d36f8c

The ABI:

[{"constant":true,"inputs":[],"name":"is_art","outputs":[{"name":"","ty
pe":"bytes6"}],"type":"function"},{"constant":false,"inputs":[],"name":"toggle",
"outputs":[],"type":"function"},{"inputs":[],"type":"constructor"},{"anonymous":
false,"inputs":[{"indexed":false,"name":"is_art","type":"bytes6"}],"name":"Statu
s","type":"event"}]

For instructions on how to do this, see the “Contracts” pane in EtherWallet.

Seeking

seeking

This took a ridiculous amount of time to hack together, but here’s a Common Lisp function to decide the shortest angle between two other angles. It’s used in the example of seeking a point above. I can now add noise to this to make a more AARON-style pen.

(defun shortest-angle-difference (a1 a2)
  "Find the shortest positive or negative distance between two angles."
  ;; This was slowly assembled from various online sources, none of which worked
  ;; Normalize angles to 0..2pi
  (let ((from (mod a1 +radian+))
        (to (mod a2 +radian+)))
      ;; If from and to are equal (0 = 2pi radians) the angle is zero
      (if (or (= from to)
              (= (+ from to) +radian+))
          0.0d0
          (let ((angle (- to from)))
            (if (> (abs angle) pi)
                ;; Please simplify me
                (* (- (signum angle)) (- +radian+ (abs angle)))
                angle)))))

draw-something 2016

draw-something drawing February 2016

I’ve updated the Common Lisp version of draw-something to use modern technologies – Roswell, QuickLisp, ASDF 3, cl-cffi-gtk and the Plan testing library. The tests helped flush out bugs, changing my mis-uses of defmethod to defun silenced a lot of compiler warnings and that in turn helped find some more bugs. There’s now a bit of technical debt in the form of function and class names, I’ll address that later. Like the recent minara update, this is a bitrot update rather than a new feature release.

Running the code to test it reminded me of just how dissatisfied I was with the last version of draw-something. The image at the top of this post is one of the less bad results of running the code. This is an aesthetic / theoretic problem rather than a coding one. I need the same clarity that informed the earlier versions of the program (you can see a JavaScript version of one running on tumblr) in order to structure the code to output something you’d actually want to look at.
