APL logo: Difference between revisions

The ideal logo will signal that:

# ''APL is a sophisticated IT tool'' which delivers tangible benefits

[[File:APL_logo_light.png|120px|frameless|left]]

This is a cube, which is a common APL motif, e.g. used for [[APL2]] (including the book [[Books#APL2_at_a_Glance|APL2 at a glance]]), [[APL*PLUS]] and [[Dyalog APL]]. However, one quarter has been modified to resemble a leaf, thus making the cube into an [[apple]], another common association with APL. The leaf is supposed to hint at the [[Del]] which symbolises [[function]] definition and has been used in application icons for [[APL+]] and [[APLX]]. The green colours come from [[IBM]]'s modern '''Carbon''' design to honour IBM's role APL's history. The lettering spells out "APL" while also hinting at APL's usage of special [[glyphs]]; here <code>⍝⍴⌊</code> which look very close to the forms found in the widespread ''APL385 Unicode'' [[font]].

[[File:Script logo filled.png|120px|frameless|right]]

This [[apple]] logo is a basic update of [[IBM]]'s classic "I like APL" promotional, but with the leaf styled as a filled [[Del]] which symbolises [[function]] definition and has been used in application icons for [[APL+]] and [[APLX]].  The colours comes from [[IBM]]'s modern '''Carbon''' design to honour IBM's role APL's history. The script lettering commemorates APL's origins as handwritten notation and at the same time symbolises the ease with which APL is written. On dark backgrounds, the lettering would be produced in white rather than black. The logo also exists as a filled green version.

This logo follows the style of the logos of JavaScript and its relatives/derivatives, but can optionally be made to stand out more with the distinctive [[power]] glyph.

[[File:Plain Ellipse.png|120px|frameless|left]]

This is a plain ellipse designed by Juda Brudzewsky. It is similar to the logo of [[wikipedia:PHP (programming language)|PHP]], using the warning red from IBM's Carbon design. The font is reminiscent of [[wikipedia:Clarendon (typeface)|Clarendon]] used for the covers of IBM's manuals at the time when APL first appeared. Note that [[APL\360]]'s name was originally always styled in italics, technology permitted.

The thinking here is an APL Logo for general use and promoting the APL language has to be distinctive (so people notice and remember it), has to include the letters APL (as the people we want to attract will mostly not know what APL is), has also to include the words "A Programming Language" (to destinguish it from other instances of "APL") and should ideally be in 3D  or use some other means to emphasize that APL can process Arrays with complex structures and multiple dimensions. The challenge is to get all that into 120 pixels - assuming that is indeed the typical size for the Logo in use. This is a first stab and lots of variants of this basic idea are possible, bronze with black or white backgrounds, for example; which I happen to like but has the additional benefit that no other Program Language Logos use this colour. It shows up well at 16 pixels on a white background, but not on black, sadly.

A version of the Lamp Rho Downstile logo in a box with matching rounded corners. This has the benefit of working well in 16px icon size, but can also be custom drawn as pixel art. Variations include a brutalist version and zoomed pixel art with or without faint grid.
