It's actually quite refreshing to see a game that challenges your powers of observation and creation without also claiming to increase your IQ to that of a Vulcan science officer. Most every other game in iCanSketchIt's league promotes its classroom-style gameplay with an often ill-advised educational quotient. No one likes educational games - learning is for squares.
But that doesn't mean that mental, or in this case artistic, challenges are unwelcome. The developer's challenge is to take a math quiz or word puzzle and disguise it as a fun and frivolous video game - not give us homework to do. In that respect, iCanSketchIt puts itself forward as a simple and casual game; not an educational companion, which is definitely a bonus.
