I found a way!

import viz
viz.go()

menuScene = viz.addScene()

menuView = viz.addView()
menuView.setScene(menuScene)

menuWindow = viz.addWindow()
menuWindow.setClearMask(viz.GL_DEPTH_BUFFER_BIT)
menuWindow.setPosition(0,1)
menuWindow.setSize(1,1)
menuWindow.viewpoint(menuView)

#Create root node for menu quads
menu = viz.addGroup(scene = menuScene)
menu.translate(0,1.8,5)

#Create texture to apply to quads
tex = viz.addTexture('ball.jpg')

quad = viz.addTexQuad(parent=menu)
quad.texture(tex)
quad.alpha(0.7)


def press(key):
	if key == 'a':
		menuScene.visible(viz.ON)
	if key == 'b':
		menuScene.visible(viz.OFF)
viz.callback(viz.KEYBOARD_EVENT, press)

viz.add('gallery.ive')
