This is what Stephen Wolfram uses in his blog on the IWatch demo. The IconRules part should show a WordCloud icon on my IPad instead it shows the random generated number in the pictogram.

CloudDeploy[
 Delayed[
  ExpressionCell[Style[RandomInteger[1000], Bold, 250, RandomColor[]],
   Background -> Black], "PNG"], "WatchApps/RandomNumber",
 IconRules -> {"IOS" -> WordCloud[RandomInteger[10, 20]]}, 
 Permissions -> "Public"]

I was expecting to see the WordCloud picture when I choose to "add to home screen" in the IPad. If I do "add to home screen" on a normal google homepage i get a g-pictogram on my IPad desktop. Anyone any idea on what went wrong?
