I have got author's permission to add this patch to Org Mode.

Here is the original thread: https://emacs-china.org/t/org-agenda/8679/8

I don't know whether this patch have to get author signed FSF papers. Might have
not exceeded the TINYCHANGE limit?

Here is the patch code.

#+begin_src emacs-lisp
;; Show Org Agenda tasks with heigh spacing based on clock time with `org-agenda-log-mode'.
;; https://emacs-china.org/t/org-agenda/8679
;; work with org-agenda dispatcher [c] "Today Clocked Tasks" to view today's clocked tasks.
(defun org-agenda-time-grid-colorful-spacing ()
  "Set different line spacing w.r.t. time duration."
  (save-excursion
    ;; (list "#aa557f" "DarkGreen" "DarkSlateGray" "DarkSlateBlue") ; dark theme
    ;; (list "#F6B1C3" "#FFFF9D" "#BEEB9F" "#ADD5F7") ; white theme
    (let* ((colors (list "#aa557f" "DarkGreen" "DarkSlateGray" "DarkSlateBlue"))
           pos
           duration)
      (nconc colors colors)
      (goto-char (point-min))
      (while (setq pos (next-single-property-change (point) 'duration))
        (goto-char pos)
        (when (and (not (equal pos (point-at-eol)))
                   (setq duration (org-get-at-bol 'duration)))
          ;; larger duration bar height
          (let ((line-height (if (< duration 15) 1.0 (+ 0.5 (/ duration 30))))
                (ov (make-overlay (point-at-bol) (1+ (point-at-eol)))))
            (overlay-put ov 'face `(:background ,(car colors) :foreground "black"))
            (setq colors (cdr colors))
            (overlay-put ov 'line-height line-height)
            (overlay-put ov 'line-spacing (1- line-height))))))))

(add-hook 'org-agenda-finalize-hook #'org-agenda-time-grid-colorful-spacing)
#+end_src

If this patch can be merged. I will submit an PATCH format file.

BTW, about this patch, I know using hook is a user hack way. In real patch, I
will add a defcustom option to enabled by default (WDYT?). and loaded in
org-agenda finalize position.
