While I do LOVE the Yellow Submarine iPad app (it's chock full of great videos and full-length music files), I had a tough time explaining to my 4-year-old daughter why the illustrations were so, um.....trippy.
"Yes, sweetheart, people did draw funny pictures back in then, didn't they?"
Which brings me to my next trippy toy for trippy kids.
How exactly do you suggest I explain Burning Man to my kids?!
