I think that the consensus that I took away was that it is best to learn as the need arises, rather than trying to swallow the whole thing at once.

Where's your lava lamp?

Agreed. I'm afraid we can't help you anymore until you get one and post pics. ;)

The desk is over a grand ... $$$ eeeeek.   WOW!!!
 
Husker O'le buddy and pal,  do you need a new Sonar Friend...  LOL     

Believe me, I didn't pay near that - I found one used online.  Felt fortunate to find that - the market for inexpensive desks that have a slide out tray for an 88 key workstation is....minuscule.
 
Actually, most things you see in the pic were purchased used.  
 
And as for those lava lamps....

Try Spencer Gifts at your local mall. They have a large selection at the store here at the Everett Mall, and the store manager is a bona fide lava lamp expert/consultant. The Lava Lamp Store has a good online selection, and prices appear to be very good - but with shipping they cost the same as buying locally.

I have a classic blue lava lamp.  
 
Plus a Lava Lamp Aquarium!!!

Do lava lamps help one learn about Sonar?

Yes.

No.
