# Random Arts Twitter Bot

This project implements a Twitter bot (@RandomArtsBot) that generates random art using your message. To test it out, send a message to the bot using the following syntax.

An `expression`

is made up of `functions`

and `primitives`

.

**Primitives** : `x`

, `y`

, `const`

**Functions** :

`+`

e.g.`(+ x y)`

`-`

e.g.`(- x y)`

`*`

e.g.`(* x y)`

`/`

e.g.`(/ x y)`

`sin`

e.g.`(sin x)`

`cos`

e.g.`(cos x)`

`tan`

e.g.`(tan x)`

`sqr`

e.g.`(sqr x)`

`sqrt`

e.g.`(sqrt x)`

`mod`

e.g.`(mod x const)`

`well`

e.g.`(well x)`

`tent`

e.g.`(tent x)`

`max`

e.g.`(max x)`

`min`

e.g.`(min x)`

`avg`

e.g.`(avg x)`

`lvl`

e.g.`(lvl x y const)`

`mix`

e.g.`(mix x y const)`

You can mix & match different functions together, for example:

`(+ (tan x) (cos y))`

`(+ (mod (* (sin y) const) (mod x y)) (well (+ (sin x) (sin y))))`

`(mod (avg x y) (mix (well y) (tent (cos (+ x const))) const))`
