This logo is a reinterpretation based on the classic APL [[apple]] with the leaf styled as a filled [[Del]] which symbolises [[function]] definition and has been used in application icons for [[APL+]] and [[APLX]]. The green colour comes from [[IBM]]'s modern '''Carbon''' design to honour IBM's role APL's history. The apple is subdivided into a rectangular pattern which is supposed to invoke a [[matrix]] and the middle row in turn holds three 4-row, 3-column [[Boolean]] matrices to spell out "APL" as bitmaps. This matrix of matrices hints at APL's multi-dimensional [[nested array]]s.

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 [[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]].
