I really appreciate the ideas for creating things out of paper with tape from KnittingMama and doubtfulguest.

Yesterday, I made up a little box with random things like cardboard, straws, craft sticks, toilet paper rolls, glue, and tape and didn't really say much about it. But DS noticed it, asked about it, then entertained himself for about an hour. He also raved about the activity to his papa, saying that he really wanted to play with papa some time.

Score!
