Task Force - Cupholders, NOT in the Seat or Center Console?

[Dan in Pasadena]

Does anyone have a somewhat nice suggestion for how to make a cup holder in our trucks other than between our thighs,

I have a stock bench seat and no intention of installing a center console. I don't want to drill any visible holes. I'm owndering about something that might clip or bolt onto the underside lip of the dash that could be pushed aside when not in use. Ideas? Photos would be best.

PS: It ain't a Porsche (nor a minivan) so don't anyone get an attitude about cupholders being "just wrong" or some such in our trucks.

P.S. I hate those plastic things that hang on the window ledge.
