Elegance
The line    between frivolous   and consequential   motion  design  is  an  easy    one to  discern:
does    a   particular  piece   of  motion  design  satisfy one of  the best    practices   discussed   in  the
“Utility”   section of  this    chapter?    If  not,    remove  it. It’s    frivolous,  and it’s    jeopardizing    the
usability   of  your    UI.
Don’t be frivolous
To  hone    your    judgment    about   what    is  frivolous,  download    the most    popular apps,   play
with    each    extensively,    and judge   whether they    feature animation   to  a   greater or  lesser
extent  than    your    app does.   Play    close   to  attention   to  what    each    animation   conveys,    and
why it  conveys it. If  you feel    that    these   apps    use animation   to  a   much    lesser  extent  than
yours   does,   consider    toning  back    the motion  design  in  your    UI.
There’s one exception   to  this    don’t-be-frivolous  mantra—read on!Your one opportunity to be frivolous
A   page’s  loading sequence—when   all of  your    elements    animate into    view    from    an  initial
state   of  invisibility—is your    one opportunity to  be  over-the-top    and frivolous   with    your
animations. Why?    Because this    sequence    happens only    once,   and it  won’t   repeatedly  get
in  the way of  the user’s  interaction with    your    site.   Also,   this    is  your    moment  to  leverage
your    motion  design  skills  to  deliver a   great   first   impression  on  your    site.
