One of the original “I spy: A book of picture riddles” books is now available online for free at the Children’s Library.
These kinds of games are great tools for Beginning English Language Learners to acquire vocabulary. Even though the book isn’t interactive, it could certainly be projected on a whiteboard and students could circle the objects with a marker (of course, if you had a hard copy of it you could do the same on a document camera).
I’m adding the link to The Best “I Spy” (Hidden Object) Games For Vocabulary Development.
Thanks to Keisa Williams for the tip.
